Cluedo

One of the most interesting game shows ever was based on intelligent, attention, and improvisation, as well as Anthony E. Pratt's classic board game. Mrs. Elizabeth Peacock is a wealthy widow living in Arlington Grange with her stepdaughter, the seductive Miss Vivienne Scarlet, and her faithful maid Mrs. Blanche White. Every weekend, she invites her best friends over. They are Professor Peter Plum, Reverend Johnathan Green, and Colonel Michael Mustard. Someone new will usually be thrown into the mix, whom everyone will have a motive of sorts to kill. This will be a short film shown to two teams of celebrities, who will than question the suspects and try to fit together whodunit, where, and how. Then they would make an accusation, and eventually the killer would come clean and a film showing the murder being committed would be shown. There was no actual prize for the winner save the satisfaction that they were better sleuths than the other team. Every season (and the Christmas episode) had a completely new cast.
