The rules of the game are simple: don’t die. A hanger-on, a fading starlet, a has-been, a never-was, and more gather for a game of whodunit on the yacht of an eccentric movie producer (James Coburn). As the seas rise, so do the stakes, and soon a bevy of mounting secrets threaten to sink the ensemble’s island getaway. Starring the greatest assemblage of stars this side of Hollywood Squares — Raquel Welch, James Mason, Ian McShane, Dyan Cannon, and more — this one-off, razor-tongued puzzler from screenwriters Steven Sondheim and Anthony Perkins is to die for. Simply put: Tinseltown’s a real bitch.
