There are certain films that age like cinematic fine wine, slowly revealing themselves as consummate movie-movies. 1973's "The Last of Sheila" is one such film.
Several celebrity chums are invited aboard wicked Hollywood producer Clinton Green's (James Coburn) yacht for a cruel game of "guess the deep, dark secret." Everyone has one; but naturally some are more wicked than others. And one leads to murder.
An offbeat mystery full of fine acting and actual surprises.
Note: The film was written by actor Anthony Perkins (1960's Psycho) & stage genius Stephen Sondheim, who started this film as a basis of a party game they created. Perkins and Sondheim won the 1974 Edgar Allen Poe Award from the Mystery Writers of America for Best Motion Picture Screenplay.
Starring: Richard Benjamin, James Coburn, James Mason, Dyan Cannon, Joan Hackett, Raquel Welch, Ian McShane.
