James Coburn makes a cameo appearance in the movie-within-a-movie--he pilots a light plane.

CALIFORNIA SUITE is a classic Neil Simon comedy that takes place at the Beverly Hills Hotel during the weekend of the Academy Awards celebration. Herb Ross's film follows the misadventures of four groups of guests, including a divorced couple battling over the custody of their daughter (Jane Fonda and Alan Alda), a husband who gets caught with a hooker in his room by his wife (Walter Matthau and Elaine May), a British actress nominated for an Oscar and her straying gay husband (Maggie Smith and Michael Caine), and two competing doctors and their wives forced to share a hotel room (Bill Cosby and Richard Pryor).
