The "recommend a scary movie" for Halloween thread

[LavCat]

The "always on around Halloween" movie that I found the most terrifying as a child was The Birds. Maybe the terrifying factor was that it starts with something that's so familiar to everyone- a murder :) of crows. I still think a synchronized flock of birds is awe-inspiring today, though hardly terrifying. Crows are now some of my favorite birds.

I watched The Birds recently on DVD (I work in a library and DVD's are like free candy). The only reason I did not mention it earlier was the rule of one movie per post. I saw The Birds when it came out and I was in high school. Very good movie. The film I found most terrifying as a child was Wizard of Oz. So much for rules.
