Murder by Death(1976)

Neil Simon wrote this 1976 spoof in which virtually every famous fictional detective of the 1930s and 1940s congregate at the home of a mysterious fellow (Truman Capote) to try and solve the mystery of who's trying to kill them all. Simon's jokes are mostly obvious, and the film's real appeal is the clever concept matched with fine--sometimes legendary--actors. Peter Falk plays a very Bogart-like Sam Spade equivalent, James Coco is a Hercule Poirot wannabe, Peter Sellers does a Charlie Chan bit, David Niven and Maggie Smith are reflections of Nick and Nora.... You get the picture. Lighthearted and silly, this is cotton-candy comedy for the cast as well as viewers.
