Does anyone know of any lesser known horror movies?

I mean movies that are not as well known. Pretty much everyone knows Friday the 13th, Halloween and Nightmare on Elm Street. And I don’t mean movies like Saw or Final Destination.

I’m a huge horror movie fan and I could be missing out on some real gems. I know I can just Google it, but I’d like to hear from actual people.

It doesn’t matter if I’ve seen them or not…just start naming some. I don’t mean remakes either. I’d like the original movie.
