arrive and find Spencer's .38 on Mick; ballistics, Callahan states, will prove that "his gun … was used in all the killings." A compassionate Callahan and a vindicated Spencer leave the crime scene together. Cast Production The screenplay was initially written by Charles B. Pierce and Earl E. Smith for a separate film for Locke, but was later adapted into a Dirty Harry film by Joseph Stinson. Filming occurred in spring 1983. Many of the film's scenes were filmed in San Francisco and Santa Cruz, California. The scene where Harry chases a bank robber in the downtown business district offers a rare glimpse of the area before it was devastated by the Loma Prieta earthquake of October 17, 1989. Footage for the robbery in "Acorn Cafe" was shot at Burger Island, later a McDonald's and now the site of a hotel, at the corner of 3rd and Townsend in San Francisco. At this point in his career, Eastwood was receiving a salary that included 60% of all film profits, leaving the other 40% for the studio. Estimates had Eastwood earning $30 million for Sudden Impact. It was Locke's last film to have theatrical distribution. Part of a career-long pattern that saw her playing female protagonists much younger than herself, at 39 Locke was older than all the actors playing her rapists, and 21 years older than the youth catcalling her near the start of the movie. She was six years older than Audrie Neenan, even though the character of Parkins is clearly meant to be older than Spencer. The actress who played Locke's sister was eleven years her junior. Further, Locke was only seven years younger than the art gallery curator who calls her "child" during their short scene together.
