Continuity mistake: When Clouseau and Cato are trying to get into "Le Club Foot" they go crashing through the window of a bakery. A little later on, they go through the same hole again, yet this time there is a large undamaged wedding cake sitting there for Cato to land in. The cake couldn't have survived the first accident.
Continuity mistake: When Dreyfus and the commissioner are discussing Clouseau's death, Drefus is holding open a pink file and there is a white folder on the desk . The shot switches to Drefus standing up; the pink file he is holding is now closed and another pink file is on top of the white folder on the desk. (00:45:45)
Continuity mistake: At the end, Dreyfus gets in the elevator at the hotel at the lobby. Later on he gets joined by Simone and Scallini. They travel down to the lobby, where they all get out-including Dreyfus.
Revealing mistake: When Cato is riding the motor scooter he has taken from the ice cream seller down the cobbled street, four men jump out of his way. This shot is used twice; first as a close up then as a long shot.
Visible crew/equipment: In the first scene, when the Mercedes is turning left, you can see the crew and the camera lights reflected in the side of the car.
