Final of four appearances by Jack Lemmon in a film written by Neil Simon. The others were The Odd Couple (1968), The Out of Towners (1970), and The Prisoner of Second Avenue (1975).
This sequel to The Odd Couple (1968) was made and released about thirty years after the original. The movie is significant in film history for being one of the longest gaps between the release of the original film and a sequel where all the main lead actors actually reprise their roles. Reportedly, the picture actually holds the record for this.
This Neil Simon movie was written directly for the screen and was not based on a Neil Simon play as many of his other films had been, such as the original The Odd Couple (1968).
Upon finally reaching the wedding in San Malina Felix is yelling at his ex-wife. He claims not to have seen her in half a century fifty years. Their daughter's got to be in her late twenties or mid thirties.
