DC: The Exorcist stairs | Video | Pop Pilgrims | The A.V. Club
This is interesting. It doe show why 70s movies are better than modern ones. They didn't have CGI so the director made the stuntman fall down 97 steps twice and turned the possessed girl's bedroom into a freezer so it would look more real. Also when the priest was getting last rights after committing suicide the actor, an actual Jesuit priest, giving him last rights wasn't intense enough so the director slapped him around.
I must visit these stairs, for I do so love this movie.
