Money, Dear Boy: Peter Sellers was very negative about the film - he was sure that the film would be a major flop. To his shock, it was a box office smash.
Playing Against Type: Sir Alec Guiness as a strange butler may surprise people, as well as Peter Falk playing a Humphrey Bogart-style hard-boiled detective instead of his usual Columbo.
The trench coat that Peter Falk wears in several scenes is the same one he wore on Columbo.
