18. The Believer
The Believer is the story of a violent, troubled young American neo-Nazi who spends his days preaching hatred, beating up African Americans and planting bombs in synagogues. The twist? He was raised as an Orthodox Jew. It's an even stranger and more disturbing movie when you know it's based on a real person: Daniel Burros, a Jewish American who was also a Klansman and American Nazi Party member in the 1960s.
