The Last of Sheila script was written by Stephen Sondheim and Anthony Perkins. It starts as a bunch of friends having a week long party aboard a yaht, but turns into a murder mystery. The host is Clinton Greene (James Coburn), a movie producer. The guests include Alice Wood (Raquel Welch) and her manager husband, Anthony (Ian McShane); screenwriter Tom Parkman (Richard Benjamin) and his wife Lee (Joan Hackett); Christine (Dyan Cannon) who is a talent agent; and director Phillip Dexter (James Mason). A year earlier at a similar party, Greene's wife was killed by a hit and run driver. He has devised a game in her honor in which he divulges secrets of members of the party. This gets him killed on the second night. He had distributed cards with a secret to be revealed to each of the party, "You are a shoplifter, you are a homosexual, you are an ex-convict, you are an informer, you are a little child molester, you are a hit and run driver." But it turns our one of the company had changed his card from "you are an alcoholic" to "you are a hit and run driver," Lee admits she was the hit and run driver. She had been drinking. She also admits to killing Greene. She ends up dead from apparent suicide the next day, having cut her wrists.
The case is apparently resolved, but to Dexter something does not seem right. Greene had said the slues were available without leaving the boat. He notices a picture taken the first day. each person is below a letter of the boat name, Sheila. Except the card, hit and run driver does not match. That person is under the A, for alcoholic. He presents his information to Parkman, accusing him of changing the card, and being responsible for the two murders. He had framed his wife for the murder of Greene, as he was already dead when she accidently struck him. He admits to doing it as he was unhappy in marriage and was to inherit her $5,000,000. Christine overheard this, and she and Dexter agree to keep quiet if he uses the inheritance to fund their next picture.
This movie is very entertaining. He has a very good cast. However the story was a bit confusing with the murderer not being the murderer. There is a book based on the movie, but I noticed it is very expensive as a collector's item.
