Zoolander
Zoolander was banned in a few different places for some different reasons. It was banned initially in some Middle Eastern and South Pacific countries because of its vaguely homosexual undertones. But, it was most notably banned by the Malaysian government because the plot of the film centers around Derek Zoolander being a sleeper agent destined to murder the prime minister of Malaysia.
The Birth of a Nation
If you don't know about this movie, you're probably living a more blissful life than most. The Birth of a Nation depicts a fictional America that was "saved" by members of the KKK. This movie is horrendously racist, whitewashed, and factually incorrect. The Birth of a Nation is so unbelievably ethically and morally reprehensive that it has been banned in Ohio, Kansas, West Virginia, Vegas, Pittsburgh, and Chicago.
