Five famous literary detective characters and their sidekicks are invited to a bizarre mansion to solve an even stranger mystery.
Myrna Loy was originally offered the part of Dora Charleston (a role that was a spoof of the character that she had played in The Thin Man (1934) franchise) but she declined, later stating that "it would have been ridiculous to have Myrna Loy doing Myrna Loy". She also stated that she didn't want her "ass pinched by David Niven".
Jamesir Bensonmum: Oh, it's nothing, sir. Just the cat.
Sidney Wang: That cat? You feed cat dog food?
Jamesir Bensonmum: I'm afraid he's a very angry cat, sir. Mr. Twain had him "fixed," and he didn't want to be.
At one point, Monsieur Perrier is separated from the others by a locked door. Sam Diamond solves the problem by shooting out the lock. However, later, when he and Miss Skeffington are locked in their bedroom, it doesn't occur to Diamond to free them using the same method.
Opening credits: Starring (In Diabolical Order)
The original ABC Network broadcast of the film contained four additional scenes not found in the theatrical or DVD version. 1. Jessica Marbles' taxi driver (played by Peter Sellers) requests a large fare. 2. Dick and Dora Charleston narrowly avoid running over Tess Skeffington, who is walking back to Sam Diamond's car from a service station because she and Sam ran out of gas. Satisfied that Tess is all right, the Charlestons simply drive off, leaving her there. 3. When Willie Wang covers up the body of Twain, he finds a note in Twain's hand and smugly announces this to the others. 4. As the detectives drive away from Twain's house at the end of the film, Inspector Wang and Willie pass another car carrying Sherlock Holmes (Keith McConnell) and Dr. Watson (Richard Peel) heading towards the Twain home. When Willie asks his father "Why didn't you warn them?" Wang replies "Let idiots find out for themselves."
