Kevin Smith created the cult classic, Clerks, a movie that was widely praised. However, Kevin Smith also made a movie called Dogma, that was subject to so much controversy it's almost hard to imagine how he got away with making this movie.
Here is a brief description of the movie: "An abortion clinic worker with a special heritage is called upon to save the existence of humanity from being negated by two renegade angels trying to exploit a loophole and re-enter Heaven." And yes, the movie is a comedy.
As protesters gathered outside of a movie theatre trying to steer people away from the film, Kevin Smith protested alongside them. Of course, none of the protesters were aware that it was Kevin Smith - and he never admitted it to the news!
When asked why he was protesting the movie, he said "I don't think it stands for anything positive." He was then asked what he thought the movie stood for, and he said "I don't know, but I've been told not good."
