The Last of Sheila (1973) - starring Dyan Cannon, James Coburn, Raquel Welch, James Mason, Ian McShane, Joan Hackett & Richard Benjamin.
A year after Sheila is killed in a hit-and-run, her multi-millionaire husband invites a group of friends to spend a week on his yacht playing a scavenger hunt-style mystery game. The game turns out to be all too real and all too deadly.
It was written by Anthony Perkins & Stephen Sondheim - apparently inspired by the elaborate games and scavenger hunts they planned for their friends.
The plot seemed like it would be right up my murder-mystery-adoring alley, but while watching it I wasn't exactly consumed with an intense curiosity to figure out the puzzle. Not bad though. Not bad.
