Legend: The story goes that Stetson Kennedy revealed inner rituals and passwords of the KKK to the producers of the Superman series. The show was then supposed to have broadcast the rituals and passwords leading to ridicule of the Klan.
Real Story: The Adventures of Superman did broadcast a 16 episode storyline in June 1946 called "Clan of the Fiery Cross" which portrayed the Klan in a very bad light. However, the amount of inside information about the KKK that was revealed on the show appears exaggerated. A review of all 16 episodes of the "Clan of the Fiery Cross" storyline reveals that no passwords were revealed on the air and only one ritual was portrayed.
