Reportedly, actress Brooke Shields's salary for her role as Kate was apparently US $250,000 plus a percentage of the profits according to a contract filed with the Los Angeles Superior Court of California, USA being reported in an article published in the 15th November 1978 issue of 'The Los Angeles Times' newspaper.
George Burns plays a retired vaudevillian in this film as he had recently done in The Sunshine Boys (1975). Burns had been having a career comeback with the comedy film The Sunshine Boys (1975) which was his first feature film appearance since World War II. In The Sunshine Boys (1975), he played faded vaudevillian Al Lewis, who has a difficult relationship with his former partner Willy Clark (Walter Matthau). The role was met with critical success and Burns won the Academy Award for Best Supporting Actor. At age 80, Burns was the oldest Oscar winner at the time. His record was broken by Jessica Tandy for 'Driving Miss Daisy' (1989).
