No screenwriter is listed in the credits of the movie whose original script was in fact written by Francis Veber. In the DVD commentary, director Philippe de Broca explains that he thought that the character of Christine needed to be fleshed out. Veber disagreed and eventually director Jean-Paul Rappeneau was called to settle the question. Rappeneau agreed with de Broca and both of them rewrote part of Veber's script. Veber made strong reservations about the rewrite, and after seeing the finished movie, asked that his name be removed from the credits.
