Sergeant François Chevalier is an assistant to Chief Inspector Charles Dreyfus and Chief Inspector Jacques Clouseau. He generally observes his superiors' interactions with Inspector Clouseau (and subsequent emotional breakdowns) with placid bemusement. André Maranne, a French actor, played François in six Panther films.
In Son of the Pink Panther, he was replaced by Dermot Crowley. In A Shot in the Dark, Trail of the Pink Panther and Curse of the Pink Panther he is referred to as Sergeant Francois Duval whereas in the three sequels of the 1970s he is Sergeant François Chevalier. In the 2006 reboot, Philip Goodwin plays a similar character named Renard, who is the Deputy Chief and assistant to Chief Inspector Dreyfus. Goodwin returned as Renard in the 2009 sequel.
