9 Behind-the-Scenes Secrets of Movie Monster Makers

Almost since the beginning of movies, people have been trying to use the medium to conjure up fantastic creatures. From Godzilla to Gremlins, there’s nothing like a hideous monster or a furry freak of nature to inspire fear and glee in the audience. The artists, technicians, and designers who create these beasts are highly talented, highly specialized—and highly imaginative. Mental Floss spoke to a few for some insight into the fanciful world of monster making.

1. CREATURE EFFECTS HAVE COME A LONG WAY SINCE GUYS IN RUBBER SUITS.

The earliest creature features typically involved a guy in a rubber suit terrorizing Tokyo or carrying off a damsel in distress. Today’s creatures are much more complex and believable, thanks to new varieties of silicone rubber, upgrades in animatronics, new forms of design software, and the development of CGI.

“Special Effects as an industry is always evolving, and products and materials are expanding and becoming more readily available than ever before,” says Stuart Rowsell, a creature technician and founder of Bloodhound FX in Australia who has worked on films including Star Wars: Episode II (2002) and III (2005), Superman Returns (2006), Mad Max: Fury Road (2015), and Alien: Covenant (2017).

3D printing is also shaking up the industry. Lino Stavole, a creature engineer at Spectral Motion based in Los Angeles, founded 3D scanning, printing, and engineering company Behold 3D to cater to the needs of the entertainment industry. Stavole tells Mental Floss that his company used 3D printing in silicone to create an alien creature for the movie V/H/S in just two days, a process that once required several more. “That really opened my eyes to the potential of what technology can do,” he says. 3D printing is also pushing boundaries in terms of design intricacy—Stavole says a creature he helped create for Netflix’s planned reboot of Lost in Space incorporates about 400 different 3D-printed parts.

2. BUT SOMETIMES, THE CREATURE IS STILL A GUY IN A RUBBER SUIT.

Technological advances have by no means pushed the classic creature suit aside, however—particularly when enhanced with a little digital magic or combined with other techniques like puppetry. A suit offers certain advantages over digital or animatronic creations, after all: “Fluidity of movement is usually why the guy in the suit is required,” Rowsell tells Mental Floss. “They can run through corridors, crawl through water, caves, tunnels, and react in close quarter fighting with characters. Often it is a lot easier to make a creature suit than it is to make an animatronic puppet.”

3. A SINGLE CREATURE OFTEN REQUIRES MANY DR. FRANKENSTEINS.

Bringing a creature to life is a big job, one usually beyond the capacity of any single designer or artisan. The traditional skills involved include concept design, body casting, sculpting, molding, and painting, while more modern skills like computer animation, digital design, and engineering now round out the list. The broad array of skills required means that making a creature is typically a team effort—and participants tend to specialize. “A lot of people think you’re going to be building a creature from design to completion, but that’s not normally the case. It’s very faceted,” Stavole says.

Of course, some creature artists are the full package. Rowsell says he’s never specialized, and being competent in both design and the various aspects of fabrication has allowed him greater control over the final product. “My business relies on mostly myself,” he says, “so I have quality control and I only have myself to blame if it goes wrong!”

4. THE BEST CREATURE DESIGNERS HAVE TWO BRAINS.

Regardless of specialty, the best creature artists are typically those who are able to think in two different ways. Stavole compares the two mindsets to aliens living on two different planets. “You have an alien on one planet who is like a Vulcan,” he says, “and Vulcans like science, so this brain of a creature designer knows about anatomy, physiology, biology, entomology, and physics—that is the science part of creature design.” The other planet is populated by artistic types. “They communicate with pictures and sculptures, but they also have to communicate history and character with creature design,” he says. Stavole explains that, as a natural Vulcan, he works to help the artists and designers on a creature team understand which sorts of structures will help their design move more naturally.

Given these differing approaches, communication is key. Stavole says he has a deep respect for specialists, but adds “the people who have a more complete overview of things tend to be the best communicators and have the best results.”

5. ONE CREATURE MIGHT ACTUALLY BE MANY CREATURES.

It’s a fact of movie magic that a creature presented as a single entity on screen may actually consist of several different versions used in tandem to create the illusion of life. Rowsell explains that while working on the 1999 movie Komodo with John Cox Creature Workshop, the creature crew made several versions of the giant lizards that appear in the film, including full-size animatronic- and puppeteer-driven komodos, as well as both full-length and wheelbarrow-style (i.e. just the front half on a wheelbarrow rig) creatures. A fully CGI lizard was also created “for the wide shots of the komodo’s faster and deadlier action," Roswell adds.

The luxury of having many creatures to work with, however, is very dependent on budget. Stavole points out that some productions will try to make one version of a creature work throughout a film, because it’s more cost-effective.

6. EVEN KING KONG HAS TO STICK TO A BUDGET.

And yes, even fantastical creatures have money problems. “The creature effect on any feature film or commercial depends on the budget. Usually the production company wants 10 thousand dollars to look like one million dollars,” Rowsell says. Budget is often the determining factor in whether a creature is rendered entirely practically (i.e. in physical materials), entirely digitally, or a combination of the two. It also influences details like whether a production can afford to pay a day rate for a puppeteer to manipulate elements like tails or wings—which often gives a more natural feel than rendering those elements digitally. “It is essentially our job to make as convincing as possible an original-looking creature within the deadlines and budget that performs on-set without falling to pieces,” Rowsell explains.

7. THEIR CREATIONS ARE INSPIRED BY REAL LIFE.

When it comes to the design process that precedes any crafting or building, creature artists draw inspiration from the natural world. They study animal and plant life, and borrow elements of bone structure, skin texture, and physical movement. (Interestingly, Rowsell worked in an abattoir before becoming a full-time artist, where he got a crash course in anatomy and internal organs. He says he recalled the horrible things he saw there when designing the innards of the lizards on Komodo).

They must also take into account another earthly presence: the director. “The director’s vision is paramount to any film,” Rowsell explains. And while the designers may draw on a broad array of sources and render hundreds of drawings of a creature, it is the director who makes the final call when it comes to design.

8. … AND SOMETIMES BY VISITS TO THE MORGUE.

Creature design does involve anatomy, but the morgues designers rely on don't house bodies. In this case, “morgue” refers to a collection of images and ephemera, long a mainstay of artist repertoires and newspaper industry archives.

Stavole, who considers himself to be more of a creature engineer or artisan than a designer, says that when he does take on design, he likes to work with a morgue. For him, this means doing a search of libraries and the internet for images, consulting with various people for ideas, and throwing everything he finds into a sort of creative stew. From that stew, surprises can emerge. “Happy accidents can happen and ideas from one project can get incorporated into another project,” he says.

9. MANY OF THE BEST CREATURES ARE PART PRACTICAL AND PART DIGITAL.

While advances in digital technology have changed the movie creature landscape, they’re unlikely to eliminate the need for practical effects and many traditional techniques any time soon. “Many SPFX artists were worried in the early '90s that CGI would end the industry,” Rowsell says, “but CGI has been very good to the special effects industry. It has enhanced it.”

According to Rowsell, working with practical creature effects comes with a host of considerations: foam rubber creatures or suits can tear or break down under wear; they can lack realism; and unlike a purely digital creation, they cannot be completely changed in post-production. But CGI can seem fake or end up looking like a video game. “I can still see (CGI) as a flat animation from a mile away,” he says, “whereas practical effects have substance.” The ideal situation, then, is a bit of both worlds: practical elements to add substance and weight, and CGI elements to augment the effect. “Today’s creature effects, when they work best,” Rowsell adds, “are 50% practical and 50% CGI-enhanced.”

11 Behind-the-Scenes Secrets of TV Meteorologists

The first weather forecast to hit national network television was given in 1949 by legendary weatherman Clint Youle. To illustrate weather systems, Youle covered a paper map of the U.S. in plexiglass and drew on it with a marker. A lot has changed in the world of meteorology since then, but every day, millions of families invite their local weatherman or weatherwoman into their living room to hear the forecast. Here are a few things you might not know about being a TV meteorologist.

1. SOME PEOPLE JUST NEVER MASTER THE GREEN SCREEN.

On-camera meteorologists might look as if they’re standing in front of a moving weather map, but in reality, there’s nothing except a blank green wall behind them. Thanks to the wonders of special effects, a digital map can be superimposed onto the green screen for viewers at home. TV monitors situated just off-camera show the meteorologist what viewers at home are seeing, which is how he or she knows where to stand and point. It’s harder than it looks, and for some rookie meteorologists, the learning curve can be steep.

“Some people never learn it,” says Gary England, legendary weatherman and former chief meteorologist for Oklahoma’s KWTV (England was also the first person to use Doppler radar to warn viewers about incoming systems). “For some it comes easily, but I’ve seen people never get used to it.”

Stephanie Abrams, meteorologist and co-host of The Weather Channel’s AMHQ, credits her green screen skills to long hours spent playing Nintendo and tennis as a kid. “You’ve gotta have good hand-eye coordination,” she says.

2. THEY HAVE A STRICT DRESS CODE.

Green is out of the question for on-air meteorologists, unless they want to blend into the map, but the list of prohibited wardrobe items doesn’t stop there. “Distracting prints are a no-no,” Jennifer Myers, a Dallas-based meteorologist for Oncorwrites on Reddit. “Cleavage angers viewers over 40 something fierce, so we stay away from that. There's no length rule on skirts/dresses but if you wouldn't wear it to a family event, you probably shouldn't wear it on TV. Nothing reflective. Nothing that makes sound.”

Myers says she has enough dresses to go five weeks without having to wear a dress twice. But all the limitations can make it difficult to find work attire that’s fashionable, looks good on-screen, and affordable. This is especially true for women, which is why when they find a garment that works, word spreads quickly. For example, this dress, which sold for $23 on Amazon, was shared in a private Facebook group for female meteorologists and quickly sold out in every color but green.

3. BUT IT’S CASUAL BELOW THE KNEE.

Since their feet rarely appear on camera, some meteorologists take to wearing casual, comfortable footwear, especially on long days. For example, England told the New York Times that during storm season, he was often on his feet for 12 straight hours. So, “he wears Mizuno running shoes, which look ridiculous with his suit and tie but provide a bit of extra cushioning,” Sam Anderson writes.

And occasionally female meteorologists will strap their mic pack to their calves or thighs rather than the more unpleasant option of stuffing it into their waistband or strapping it onto their bra.

4. THERE ARE TRICKS TO STAYING WARM IN A SNOWSTORM.

“In the field when I’m covering snow storms, I go to any pharmacy and get those back patches people wear, those heat wraps, and stick them all over my body,” explains Abrams. “Then I put on a wet suit. When you’re out for as long as we are, that helps you stay dry. I have to be really hot when I go out for winter storms.”

5. THERE’S NO SCRIPT.

Your local TV weather forecaster is ad-libbing from start to finish. “Our scripts are the graphics we create,” says Jacob Wycoff, a meteorologist with Western Mass News. “Generally speaking we’re using the graphics to talk through our stories, but everything we say is ad-libbed. Sometimes you can fumble the words you want to say, and sometimes you may miss a beat, but I think what that allows you to do is have a little off-the-cuff moment, which I think the viewers enjoy.”

6. MOM’S THE AUDIENCE.

Part of a meteorologist’s job is to break down very complicated scientific terminology and phenomena into something the general public can not only stomach, but crave. “The trick is … to approach the weather as if you're telling a story: Who are the main actors? Where is the conflict? What happens next?” explains Bob Henson, a Weather Underground meteorologist. “Along the way, you have the opportunity to do a bit of teaching. Weathercasters are often the only scientists that a member of the public will encounter on a regular basis on TV.”

Wycoff’s method for keeping it simple is to pretend like he’s having a conversation with his mom. “I’d pretend like I was giving her the forecast,” he says. “If my mom could understand it, I felt confident the general audience could as well. Part of that is also not using completely science-y terms that go over your audience’s head.”

7. SOCIAL MEDIA HAS MADE THEIR JOBS MORE DIFFICULT.

Professional meteorologists spend a lot of time debunking bogus forecasts spreading like wildfire across Twitter. “We have a lot of social media meteorologists that don’t have necessarily the background or training to create great forecasts,” Wycoff says. “We have to educate our viewers that they should know the source they’re getting information from.”

“People think it’s as easy as reading a chart,” says Scott Sistek, a meteorologist and weather blogger for KOMO TV in Seattle. “A lot of armchair meteorologists at home can look at a chart and go ok, half an inch of rain. But we take the public front when it’s wrong.”

8. THEY MAKE LIFE-OR-DEATH DECISIONS.

People plan their lives around the weather forecast, and when a storm rolls in, locals look to their meteorologist for guidance on what to do. If he or she gets the path of a tornado wrong, or downplays its severity, people’s lives are in danger. “If you miss a severe weather forecast and someone’s out on the ball field and gets stuck, someone could get injured,” says Wycoff. “It is a great responsibility that we have.”

Conversely, England says when things get dangerous, some people are reluctant to listen to a forecaster’s advice because they don’t like being told what to do. He relies on a little bit of psychological maneuvering to get people to take cover. “You suggest, you don’t tell,” he says. “You issue instructions but in a way where they feel like they’re making up their own minds.”

9. DON’T BANK ON THOSE SEVEN-DAY FORECASTS.

“I would say that within three days, meteorologists are about 90 percent accurate,” Wycoff says. “Then at five days we’re at about 60 percent to 75 percent and then after seven days it becomes a bit more wishy-washy.”

10. THEY’RE FRENEMIES.

The competition for viewers is fierce, and local meteorologists are all rivals in the same race. “When you’re in TV, all meteorologists at other competitors are the enemy,” England says. “You’re not good friends with them. They try to steal the shoes off your children and food off your plate. If they get higher ratings, they get more money.”

11. THEY’RE TIRED OF HEARING THE SAME JOKE OVER AND OVER.

“There’s always the running joke: ‘I wish I could be paid a million dollars to be wrong 80 percent of the time,’” Sistek says. “I wanted to have a contest for who can come up with the best weatherman insult, because we need something new! Let’s get creative here.”

13 Behind-the-Scenes Secrets of Movie and TV Extras

Background actors are the unsung heroes of television. Without them, most movie and TV scenes would be empty and unrealistic. But while we’re obsessed with movie stars, we never hear much about the people moving around behind them—because by design, we’re not supposed to pay them any attention. Here are a few insights on what it’s like to get paid to blend into the background.

1. Extras Are Not Professionals.

The chances of using background acting as a foray into stardom are pretty slim. “You’re not gonna get your big break as an extra,” says Claire Beaudreault, who has been an extra on shows including Orange Is The New Black, GIRLS, and Law & Order: SVU.

Most of the people you see in the background of a film or TV show have other jobs and are just doing extra work for fun. “I didn’t do it because I saw it as some backdoor into acting or anything,” says Jason Feifer, who was an extra in a scene of the 2004 film Jersey Girl. “But there are definitely people who do that.”

And there are always a few extras on set trying desperately to stay in front of the camera. “It’s a silent vie for control,” says Dillon Francis, a Los Angeles-based actor who was an extra on the movie Easy A back in 2010. “It was kind of interesting to watch. These guys would learn where the camera was going and redo their vector so they walked in front of it.” That’s a quick way to get a slap on the wrist from the director or a production assistant.

2. Extras Have to Do a Lot of Hurry-Up-and-Wait on Set.

Days on set can be excruciatingly long, sometimes lasting more than 15 hours and starting at odd times or ending at the crack of dawn. And a lot of that time is spent just sitting around waiting to be used in a scene, or repeating a single shot a dozen times. “There are days you get to set and you wait and wait and you never get used,” says Amy Rogers, a regular extra featured in TV shows including Homeland and Banshee, “or you work all day and the footage never gets used.”

Extras spend their down time in a designated “holding” area reading or playing card games. On the set of Easy A, which was set in a high school, extras had to wear backpacks stuffed with bubble wrap to make them seem full. “A fun way to distract yourself in downtime was to open up your backpack and pop bubbles,” Francis says.

3. What Looks Like Booze On Camera Isn't Actually Alcohol.

While posing as party-goers in bar scenes, extras need something to fill their cups. But film sets are no place for drunk actors, so the props team uses a number of tricks to fool the camera, some less appetizing than others. Apple juice is a good substitute for beer, according to Beaudreault: “Or it’ll be seltzer with a little food coloring in it. There will be bottles that have been cleaned out and their labels removed and fake labels put on.”

“Vinegar is sometimes used to approximate the texture and viscosity of booze,” Rogers says. “You’ll stand there with a glass of vinegar for eight hours.” And because filming can be a long and mind-numbingly repetitive process, nobody has time to replace melting ice cubes, so they’ll use gelatin ice cubes. Or, for the ultimate cheat, plastic wrap can be put in a cup filled with water to resemble crushed ice, according to Gale Nemec, who teaches a workshop for background actors. (This approach also apparently makes for festive centerpieces.)

4. Smokers Get Paid More.

When actors smoke on set, they’re usually not sucking on real cigarettes. On Mad Men, for example, the actors smoked herbal cigarettes that didn’t contain nicotine or tar (which is great, considering Jon Hamm reportedly smoked 74 of them shooting the pilot alone).

Non-union extras usually get paid minimum hourly wage, but according to Rogers, they get a small pay increase if they’re asked to smoke in a scene. “They call that a ‘bump’ in the business,” she says. The same rule applies if your car is featured in a scene. “They want boring cars that will never be noticed on screen,” says Steve D’Avria, an extra in The Hunger Games and Homeland. “My 2003 Toyota Camry has been in more TV shows than I have. You get a whole $20 for it.”

5. Extras Have Been Wearing the Same Duds for Days ...

On a film or TV set, continuity is key. To create the illusion that a scene is happening in real-time, rather than over a series of hours or days, every little detail must remain the same in each shot and from every angle. Extras are meticulously examined for accidental inconsistencies in their wardrobes. “You’ve gotta wear the same clothes every day,” Rogers says. “The production assistant will take your picture for continuity to make sure you haven’t taken off a necklace or something. For the Homeland finale, I wore a pair of leggings and a raincoat for a solid week.”

6. ... And They Usually Have To Bring Their Own—The Blander, The Better.

Background actors are usually expected to bring their own clothes to set unless the production has a large wardrobe budget. And if you were to peek into the closet of a regular background actor, you’d see hangers upon hangers of gray and dark blue clothing items. Muted colors are preferred on set to make sure extras are as unremarkable as possible. Shirts can’t have any visible logos, and white clothes are discouraged because they “have a tendency to shine like a beacon on camera,” Francis says.

If you resemble one of the principal actors, you’re probably not going to get much camera time. “On Homeland, you’ll never see them place anyone near Claire Danes who has the same hair color as her,” Rogers says.

And pro tip: never look at the camera. “One guy in The Hunger Games kept staring at the camera and they finally just told him he had to sit down,” D’Avria says.

7. Wardrobes for Extras Get Recycled.

If an extra has to wear an elaborate costume, there’s a chance it’s been used before on another set. “One outfit I wore for Insurgent was worn on Pirates of the Caribbean,” says Dawn McHargue, who has also appeared in The Hunger Games, Iron Man 3, Nashville, and Necessary Roughness.

8. Extras Are Great Mimes.

Extras often need to make a scene appear alive and bustling while at the same time remaining totally silent on set so as not to interfere with the actors’ dialogue. This means pretending to conduct a conversation without actually making any noise, and every extra seems to have their own method. “I’m either pretending to flirt with someone or gossiping about something,” Beaudreault says. Also, dance scenes are often filmed in silence and the music is added in later.

While filming a crowd scene for the movie Jersey Girl, Feifer says he spent hours pretending to applaud and cheer. “They would do entire takes where the audience would go through the whole motion but we wouldn’t clap. We would fake clap but not actually get our hands to meet.”

9. For Actors, Seasons Are Irrelevant.

It’s amazing what a little fake snow can do to transform a summer day into a winter wonderland. “Sometimes when you’re shooting a winter scene, everyone is in heavy jackets and hats and gloves and it’s actually 100 degrees outside,” Nemec says. “You can gauge whether it’s actually cold or not if breath is coming out of the actor’s mouth. If not, it’s a good bet they’ve put snow on the ground and it’s hot as all get out and everyone is playing like it’s cold.”

For indoor scenes, air conditioning has to be turned off to eliminate background noise, which makes for a sweaty situation. Between takes, overheating extras strip their layers off to cool down.

10. The Movie Stars Are Off Limits for Extras ...

“As a general rule, don’t speak to them unless they speak with you first,” advises casting director Tona B. Dahlquist.

While filming on one movie, McHargue and her fellow extras were told to avoid looking the star in the eye. “They were very adamant that we were not to go near him or touch him or we would get kicked off set immediately,” she says.

But occasionally extras get a candid glimpse of a movie star’s true personality. For example, while filming The Hunger Games, D’Avria saw Jennifer Lawrence chilling at a card table munching on M&Ms, and watched Josh Hutcherson (who played Peeta) ride around set on a BMX bike.

On the flip side, Francis was the victim of one star's on-set meltdown. “She sees me standing there and she freaks out, saying something about how she’s had a rash of stalkers lately and I’m within a 50-foot perimeter,” he says. “She’s glaring at me from the tent and a PA runs over, moves me a few feet away and says ‘sorry’ and runs away again.”

11. ... And Social Media Is a Good Way for Extras to Get Blacklisted.

Phones aren’t allowed on set and photos are strictly forbidden. “While filming Insurgent, there was a girl who took a picture of the set and shared it,” McHargue says. “Lionsgate security came from California to Atlanta and they took her away. She will never work on a set again. She’s blacklisted.”

If you’re sneaky, you can swipe a harmless item from set as a keepsake. While filming The Hunger Games, D’Avria says there were signs in the bathroom that said, “Flush the toilet or you’ll be sent to the Hunger Games.” “I borrowed that sign as a souvenir,” he says.

12. The On-Set Catering Is Pretty Good.

The quality of food on set varies depending on budget, but generally, extras eat some amazing grub brought in by professional caterers. “The food on Iron Man 3 was the best food I’ve ever had,” McHargue says. “We ate with the cast and crew and we had anything you could think of: the best steak, shrimp, lobster, and crab. The buffet table, you couldn’t see the end of it.”

The catch: You often don’t get to eat lunch until about 3 pm and dinner starts at 10 pm, according to D’Avria. Extras are advised to bring a few snacks to hold them over until feeding time.

13. Extras Can't Watch TV Like Regular People.

Once you know how a movie is filmed, it’s hard to watch it with fresh eyes. “I can’t watch TV anymore without looking at the background actors and seeing who’s doing it right and who’s doing it wrong,” Nemec says.
