The reason for this is that the original dubbing (supervised by Rainer Brandt) which was used for the theatrical showing of the movie was drastically different from the original version in terms of humor and vulgarity, so that the German TV ordered a new language track for the TV premiere of the movie which resembles the language and atmosphere of the original version of the movie much closer.

Writer/Director Francis Veber's original choice of stars for the film was Lino Ventura as Campana and Jacques Villeret as François Perrin, but Ventura refused to work with Villeret.
