The Odd Couple II is a 1998 American buddy comedy film and the sequel to the 1968 film The Odd Couple. It is the final film written and produced by Neil Simon, starring Jack Lemmon and Walter Matthau. Released nearly three decades later, it is unusual among sequels for having one of the longest gaps between the release of a subsequent film. The Odd Couple II premiered on April 10, 1998, and was a critical and commercial failure, grossing less than half of its predecessor at the box office.
