Continuity mistake: In the flashback, when the trainer kills the coach with the dart, he stabs the coach but when he takes his hand away the dart is above his hand.
Other mistake: In the final scene where the police chief is barreling through the hospital on his bed, he goes along a straight path, yet when the two inspectors and the assistant come down the stairs they come out the side of the corridor. If the police chief followed a straight path, how did they come out of the side of the corridor, and how did the bed turn around a 90 degree corner at that speed?
Audio problem: When Clouseau is in the training facilities and hears footsteps approaching, the feet sound like they are wearing high heels or football boots. However when the Russian trainer appears he is wearing trainers therefore his footsteps could not possibly have made the noise heard on his approach.
Continuity mistake: When Xania is performing her song at the Presidential Ball, she has a long feather draped down her back. During the song, the feather disappears, but at the end of the performance it re-appears.
Revealing mistake: During the opening soccer match scene, the advertisement banners in the stadium appear backwards in several shots.
