Continuity mistake: In the scene in the Beatles hotel room where Nancy Allen comes out from under the cart with the cokes on it, when she first sees the Beatles' guitars, notice that in the very first scene, the Hofner bass is left handed (the pick guard is on the left as you're looking at it), then it cuts to her, then when it cuts back to her rolling on the floor with the bass, it's suddenly right handed, then when in the last scene with her handling it, it's left handed again.
Continuity mistake: Near the end of the film when Spider Mike is rescued from a town. The Rubber Duck's truck is damaged. It loses the bullbars on the front, and the windbreaker on the roof is flattened against the roof of the cab. Yet after leaving the town, in a series of shots showing the Rubber Duck's truck. The damage disappears or varies. The windbreaker appears fixed and so do the bars, but in the next shot just the windbreaker is fixed and the bars aren't. It continues like this through a montage and then in the next scene when it cuts back to a close up of the truck both are damaged again. (01:47:40)
Continuity mistake: There is one scene in the final earthquake as Ski and Sonny are driving around the city that's being destroyed - the Trans Am gets hit from the right side, hard enough to throw the car into a small skid, but seconds later there is no damage to the car, and nothing like that was discussed during the planning of the stunt. One has to wonder if that hit was unintentional and not scripted.
Continuity mistake: The dressing that is on the evil Dr Leticia Baines's forehead keeps changing. When she is first placed on Grogan's raft, the dressing is soaked with blood. In the next few scenes it just has a small patch of blood in the centre. After she swims to rescue the boy from his canoe, she gets on the raft and the dressing is dry. In the next two close-up shots the dressing is wet (with water) and then it is dry again.
Revealing mistake: When the police officer falls down at the lake and lands face to face with the rattle snake, you can see the glass separating the actor and snake.
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.jle
Continuity mistake: As Kenny is riding the bike, to try and grab on to the ladder at the back of the camper, the rear side-marker light on the camper is missing its red lens cover. In subsequent shots the red cover is there, and then vanishes again.
Continuity mistake: When Scarface is holding Gloria as he asks "Where is it?", watch her arms - from the side, we can see her left arm is arched outward; however, from the view behind Scarface and facing Gloria, her hands are pressed together in front of herself, in a defensive position.
