Strangers on a Train is a great scary Hitchcock film. I think Joseph Cotton plays the psychotic killer who insists the bargain be kept.

Interesting that no good film version of any of Poe's wonderful macabre work exists.

The Haunting was a fine film, the original black and white version I mean, keeping to the pschological aspects that Shirley Jackson emphasized in the novel.

I mentioned Barton Fink in the other thread on re-watchable films. John Goodman plays a traveling salesman/serial killer who is both endearing and absolutely chilling. The scene at the end when Goodman appears at the end of the hotel corridor as the building is engulfed in flames is one of the scariest scenes in all of film.

The Serpent and the Rainbow had its moments, with Bill Pullman as a graduate chemistry student investigating herbs used to induce the zombie state.
