Audio problem: About 10 minutes into the movie, Howard and Eunice are standing at the head of the hotel's escalator listening to Judy define the word "propriety" as she descends; instead of diminishing in volume as it ought to, the volume in this speech stays the same and even increases a little right at the end.

Revealing mistake: When the Chinese dragon is knocking over the trash cans you can see they are all perched at an angle on the curb to facilitate being kicked over.
Hugh: I find that as difficult to swallow as this potage au gelee.
Judy: How would you like to swallow one sandwich d'knuckles?
Trivia: Much of Hugh Simon's dialogue was ad-libbed by Kenneth Mars.
