The movie was shot in the Malibu beachside home of writer and director Blake Edwards and wife Dame Julie Andrews.
Jack Lemmon's real-life son, Chris, played his movie son "Josh", and Jack's wife Felicia Farr played a fortune teller.
Because it was a non-union shoot, picketers appeared at Blake Edwards' house to disrupt shooting. Problems were resolved between Edwards and the union.
Dame Julie Andrews' stepdaughter, Jennifer Edwards (with Blake Edwards) and daughter Emma Walton Hamilton played her children in this movie.
Chris Lemmon, the look-a-like son of Jack, appeared with his father in two movies, the other being Mon père (1989).
