The 1973 version of The Exorcist.
I remember after the movie I had to walk back home it was pitch black windy and i had to walk down a 2mile old creepy railroad track, the carriages would creak in the wind and a loud bang every now and then would happen. I was 14 or 15 at the time and complety freak out:rotfl:scared sh*tless. Then when i got home i had a look under the bed:rotfl:Just in case some devil or something was hiding under there!:rotfl::rotfl:
