Three friends play a game of musical chairs with their relationships in this quirky comedy based on the hit play by Murray Schisgal. Harry Berlin (Jack Lemmon) is a deeply depressed man who is convinced his life is going nowhere -- so much so that he has decided to kill himself by jumping off a bridge. Just before he makes his big leap, Harry is interrupted by Milt Manville (Peter Falk), an old friend in high school who has struck it rich as a combination stock broker and salvage dealer. Milt is not-very-happily married to wildly neurotic Ellen (Elaine May), and is having an affair on the side with Linda (Nina Wayne), a buxom gym teacher. Milt fixes Harry up with Ellen, hoping they'll hit it off and Ellen will leave him so he can marry Linda. The ruse works, in part -- Harry and Ellen decide to tie the knot, but in the divorce settlement Ellen gets all the money, and Milt decides marriage to Linda is not all he imagined. Harry and Ellen's happiness proves to be short lived, and she begins to wonder if its too late to give Milt another chance. Jazz great Gerry Mulligan composed the film's musical score; keep an eye peeled for a bit part by a young Harrison Ford.
