Fancied watching a screwball comedy. I remember seeing this with my parents when I was a kid. They loved it, and so did I.

Turns out it stands up pretty well. Four people arrive in San Francisco and check into the same hotel. They have identical suitcases. What could possibly go wrong?

Contains what was probably the first car chase I ever saw, and remained the funniest until, I'd guess, I first saw The Blues Brothers.
