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?
Suggested correction: At 1:27:46 Inspector Dreyfus' hospital bed blows through a set of blue hospital doors. At 1:27:51 we see from a different angle, those same doors still partially open but swinging shut and then at 1:27:55 we see Inspector Clouseau and the others emerge from a different hallway, the blue hospital doors now shut behind them. Inspector Dreyfus' bed never made a turn as evidence by the doors. The trio though, for some reason took a different route chasing his bed.
Other mistake: When Ponton and Clouseau are driving the car, before the cyclist smashes in the door, the car is reflected many times on the windows. There is a black object at the rear of the car, which was not there before, and disappears the rest of the film.
