Benoît Magimel, who was at one time set to star, stepped down from the Mesrine project without informing producer Thomas Langmann, choosing instead to issue a press release. As a result of this a fight erupted on November 25th 2004 at the Intertalent talent agency between Langmann and Magimel's agent, François Samuelson, where Langmann headbutted Samuelson and broke his nose. Samuelson was on sick leave for nine days and pressed charges against Langmann.
