Movie trailers aren't what they used to be. The trailer for the 1975 movie Jaws was 3.5 minutes long and you never saw the shark, except for a short clip of a fin and a shot of the movie poster. We all wanted to see the shark, so we all paid our $2 to go to the theater. In more recent monster movies, the trailer has all the very best scenes so you can avoid the movie altogether! Here are some over-the-top sea monster movie trailers that will save you a lot of time.

Shark Attack 3: Megalodon

The more sequels a monster movie has, the bigger the monster grows. In Shark Attack 3: Megalodon from 2002, the shark is about the size of a cruise liner.

Mega Shark vs Giant Octopus

A straight-to-video film from 2009, Mega Shark vs. Giant Octopus starred '80s celebrities Deborah Gibson and Lorenzo Lamas. It made a good 2-minute movie, which was why the trailer was a hit and the movie was not.

Sharktopus

In the 2010 Sy-Fy production Sharktopus, a half-shark half-octopus creature was genetically engineered by the Navy as a weapon of war. Of course, it escapes.

Mega Shark vs. Crocosaurus

A sequel to Mega Shark vs Giant Octopus (as if we needed one), Mega Shark Versus Crocosaurus came out on video in 2010. The best part of this movie was seeing Jaleel White. Every time one of the monsters caused trouble, the words "Did I do thaaat?" went through my head.

Mega Piranha

Following the smashing success of Deborah Gibson in Sharktopus, another '80s pop star, Tiffany, was recruited for the 2010 Sy-Fy feature Mega Piranha. Brady Bunch kid Barry Williams also starred. The premiere draw an audience of over two million!

Mega Python vs. Gatoroid

Deborah Gibson must feel better about not doing the Mega Shark sequel after she was recruited for the 2011 Sy-Fy monster movie Mega Python vs. Gatoroid. It also features Tiffany, who gets eaten in this one.
