I was trying to figure out why this film, which has a 'Not Rated' category in the U.S. has been classified one step down from a Restricted rating in Canada. I realize the subject matter is adult in nature and the movie was certainly ahead of its time (1961) but honestly, I know that there are enough films currently in release with a PG rating that have subject matter ( sex,language& violence ) that must make this movie tame in comparison. Were the individuals who do this for a living having a bad day? I saw the movie on tape a few years ago and could not see anything worse than it being PG. Anybody have ideas or answers for this as it might turn some people away from purchasing it as it is a great drama by William Wyler, and besides, I have not been able to associate Audrey Hepburn with an 18A classification.
