Murder By Death - 1976 - 6/10

Five famous amateur detectives are summoned to stately Twain manor.
There, they are informed a murder shall occur at midnight, and they will not be able to solve it.
Thereby tarnishing their reputations, and leaving their host as the greatest mastermind of them all!
Written by Neil Simon, opening credits by Charles Addams, featuring a gala of stars: David Niven, Peter Sellers, Maggie Smith, Peter Falk, Alec Guinness, Elsa Lanchester …
Spoofed are Sam Spade, Nick & Nora Charles, Charlie Chan, Miss Marple, Hercule Poirot.
Heavy on gags (many wildly politically incorrect), they can be enjoyed by all, though genre buffs will relish.
