Based on the board game Clue (known as Cluedo in the UK), this is a perfect example of a gimmick movie. The plot (an amalgam of various Agatha Christie clichés) involves a number of guests invited to dinner at a spooky mansion, where they endure a murderous evening. Scripted and directed by British sitcom stalwart Jonathan Lynn in his first Hollywood venture, this is a broad, somewhat camp comedy with a vulgar edge. Originally released with three different endings, though there was only one version in the UK.

Clue finds six colorful dinner guests gathered at the mansion of their host, Mr. Boddy -- who turns up dead after his secret is exposed: He was blackmailing all of them. With the killer among them, the guests and Boddy's chatty butler must suss out the culprit before the body count rises.
