Scariest Movie Ever

This is one of the scariest movies I've ever seen. As a matter of fact, it was one of the scariest books I had read. I couldn't see the book cover without breaking into a sweat.
After I had seen the movie, I slept with the light on for about 2 weeks. When I decided to put this clip up on the blog in honor of Halloween, I had a hard time watching it. Still scaring me after 35 years. Now thats what I call scary!
