Scream while you stream these obscure horror films

Celebrate Halloween by watching overlooked movies with killer clowns, tentacled sea creatures, zombies, cannibals and a house that eats schoolgirls.

Not all horror films are scary. Some, like 1977's "House," are just plain trippy.

You probably watch the same scary movies every Halloween. Maybe you prefer watching Bruce Campbell fight off demons in " Evil Dead," or you like to watch Jack lose his mind in "The Shining" or see kids get sucked into a paranormal vortex in "Poltergeist."

No matter which movie gives you the most heebie-jeebies, once you've seen it for the 20th time, it's hard to be properly spooked. You know not to go down in the basement alone. You can pinpoint the minute when Jason or Freddie or Ghostface will start stabbing away at drunken partygoers. So why bore yourself?

This Halloween, instead of a movie marathon of the same classic horror films you love, take a chance on something new, different and downright bizarre. In fact, some of the most obscure horror films from all over the world are streaming now on Netflix, Hulu and Amazon Prime. (Horror fans outside of the US should check their preferred streaming services as well.)

Here's a list of some of the most terrifying horror films we think you might like that feature everything from killer houses to alien sea creatures. Many are indie or foreign films, but a few are rare gems made in the '70s or '80s. All are so memorable that you may find yourself watching them months after Halloween, any time you could use a good scare. Just don't blame us later for all the nightmares.
