Near the end of the film, Dr. Lentz (Ulrich Mühe) sings a song at the party onboard the ship belongs to 'Hermann Willié'. The melody is taken from a famous German seaman-song of Hans Albers: "La Paloma"!
Based upon a true story.
Mario Adorf wanted to play in this movie, preferably the role of Hermann Willié, which went to Götz George, or the role of Fritz Knobel, which went to Uwe Ochsenknecht. Adorf later admitted that he had been offended for a few years, that Helmut Dietl didn't cast him in any role.
