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.
During production, Burt Kwouk (Kato) was arrested by the police in Hong Kong after they saw him run out of a hotel and jump on a scooter to pursue the criminals. It took him several hours to convince the police that he was only doing it for a movie.
