Scariest movies Ive seen are The Texas Chainsaw Massacre (1974) And Rosemarys Baby(1968)

I first saw it in broken down little theatre preceded by an open heart surgery documentary. There were only two other people in the place, the seat next to me was smashed up and the ceiling was dripping water two seats over.
