"laughed their head off" during the play and she was hired for the film. This film marks the first collaboration of the quartet Poiré–Clavier–Reno–Lemercier, who were reunited in Les Visiteurs two years later, in 1993. Many young actresses auditioned for the role of Isabelle Fourreau. Poiré finally chose Isabelle Renauld, who was at the beginning of her career. To represent the President of the Republic, a character only seen from behind in the film, a "casting of skulls" was made to find an actor whose head looked closest to that of François Mitterrand. Shooting Stunts Initially, the scenes taking place aboard the Citroën BX had to be made on a voiture travelling, a common filming technique where the actor pretends to drive the vehicle. However, in these conditions, the travelling car can only roll at low speed and this posed problems during the shooting of the scene on the national road, where the BX is supposed to roll at 140 km / h.

Cars The film honors the Citroën range of the moment, where several contemporary models of the brand appear throughout this comedy (AX, BX, XM, CX EVASION Ambulance, C 25). All cars were loaned by Citroën: The Citroën BX Jean-Jacques Granianski (Christian Clavier) is a BX 16 TGS model 1990 Red Delage color. For the purposes of the film, no less than six BXs were used: a new BX with 2,000 km on the clock was used for "calm" scenes and on-board shots and, for the eventful or waterfall scenes, five other older cars have been made up to look like new. We see especially during the scene in the sunflower field that the BX used for this sequence is older because its interior is brown while it is gray in the new BX. The Citroën XM of General Masse (Jacques François) - that is offered Jean-Jacques Granianski (Christian
