Referring to the time it was made and the large cultural impact "Deep Throat" had I think it's justified to add it to this list of films especially when you consider that they didn't want to list the "greatest" films ever made. "Deep Throat" was the first porn movie to bring porn into mainstream. Without "Deep Throat", "Behind The Green Door" etc. the "Porno Chic" wave would have never happened. There were large crowds in front of the movie theatres (!) showing "Deep Throat" and it attracted an audience outside of the raincoaters crowd. Director Mike Nichols recommended this movie to Trumane Capote and Frank Sinatra recommended it to Spiro Agnew. Linda Lovelace became some kind of recognizable cultural item in the country. Stuff like this just won't happen anymore.
