Type “modern trailer” into your YouTube search bar and you’ll enter a magical world where enthusiastic video editors give movie trailers a makeover just for fun. HBO Max is getting in on the action, too.

The streaming service has released modern takes on the trailers for 10 classic films, all compiled into one convenient YouTube playlist. As Geekologie points out, you might want to tread carefully if you haven’t ever seen the movies—HBO Max stuck to the trend of revealing quite a lot of plot in the trailers, which some people could construe as spoilers.

Unsurprisingly, the more recent movies mesh with current trailer elements a little better than older films on the list. If you didn’t know any better, you might think Boogie Nights (1997) was a forthcoming indie flick. The contemporary, piano-heavy instrumentals backing the modern trailer for Casablanca, on the other hand, aren’t exactly enough to make the 1942 film seem like it came out in the 21st century.

Even if you’re a traditionalist who feels like the new trailers strip away the character of the original movies and give them a factory-produced quality, you might still find them useful. Today’s young people have grown up watching the incredible CGI innovations of MCU blockbusters and other comparable action films—and it’s not always easy to convince them that a seemingly low-tech thriller from the 1970s is worth the watch. Showing a teen the flashy new trailer for 1979’s Alien, for example, might pique their interest better than the classic version would.

You can watch trailers for Gremlins (1984), The Exorcist (1973), and the rest of the movies in the playlist below, or find them on YouTube.
