Ernest and Bertram
This 2001 mockumentary depicted the relationship of Sesame Street's Bert and Ernie as a scandalous, closeted homosexual scandal. While the creators of Sesame Street have not denied that Bert and Ernie are potential lovers, this adult representation of the children's characters is far too vulgar (and homophobic) to be considered appropriate for release. Legal action was taken against Peter Spears (the director of Ernest and Bertram) and he was forced to cancel all screenings of the film.
The Profit
This movie was a parody documentary about L. Ron Hubbard and how he became the cult leader behind Scientology, Hollywood's favorite "alternative" religion. No original names or likenesses were used, but the Church of Scientology was able to attain an injunction against the film. This just goes to show, money talks, and rich people have enough power to cover their tracks.
