When Casablanca was released in West Germany for the first time in 1952, seven years after WW2 had ended, the version was heavily edited (20 minutes were missing) and by the means of dubbing all references to Nazis, Vichy and the Resistence had been removed. The main character, the resistance fighter Victor Laszlo, had magically transformed into Norwegian scientist Larsen.
Before you start to think censorship... Yes, there is censorship in Germany, but not in this case. The distributor decided that more money could be made with a "denazified" version of the movie. So much for artistic control.
