"As a man you are barely passable, but as a woman you are a dog." -- Milo Perrier summing up the situation.
A mysterious man invites variations of Sam Spade, Charlie Chan, Nick and Nora Charles, Miss Marple. and Hercule Poirot to his home where he challenges them to solve a murder that will occur at midnight. The host is played by Truman Capote, and the detectives by James Coco (Milo Perrier); Peter Sellers (Sidney Wang); Elsa Lanchester (Jessica Marbles); David Niven and Maggie Smith (Dick and Dora Charleston); and Peter Falk (Sam Diamond). If there's one problem with this rather cute movie is that it's a complete farce, with no real plot (just a premise) and nothing much to hang the jokes on. As for the jokes, for every one that garners a laugh there's two that land with a thud. However, the performances are all wonderful, and there's expert support from Estelle Winwood (Miss Marbel's nurse, who now needs looking after herself); Richard Narita as Wang's son; Nancy Walker as the deaf-mute maid; James Cromwell [American Horror Story: Asylum] as Perrier's chauffeur; Eileen Brennan as Diamond's girlfriend; and especially Alec Guinness [The Swan] as the blind butler, Bensonmum. Truman Capote is no actor, but on an amateur level he isn't too terrible as Lionel Twain. On the other hand, Peter Sellers [The Wrong Box] is simply wonderful. Don't expect any coherency (even for a comedy) and you may have fun.
Verdict: Silly, hardly for all tastes, but beautifully-acted and zany. ***.
