kidnap and ransom the mayor of San Francisco. After the screenplay was finished, Hickman visited Eastwood's Carmel restaurant, The Hog's Breath Inn, and approached Eastwood's business partner, Paul Lippman, asking if he would give their effort to Eastwood. Lippman was initially hesitant, but finally agreed. Although Eastwood thought the script needed work, he liked the concept, particularly the priest with militant leanings and the portrayal of black militants, which was based on the Black Panther Party. Warner Bros., meanwhile, eager to capitalize on the success of the two Dirty Harry films, had hired seasoned screenwriter Stirling Silliphant to write a new Harry Callahan story. Silliphant wrote a script called Dirty Harry and More, in which the Callahan character was teamed up with an Asian-American woman partner named More. Eastwood liked the woman-partner angle, but felt the script spent too much time on character and did not have enough action. Eastwood then showed the Hickman/Schurr script to Silliphant, and Silliphant agreed to rewrite it. Silliphant wrote the script throughout late 1975 and early 1976 and delivered his draft to Eastwood in February 1976. While Eastwood approved, he believed the emphasis was still too much on the character relationships rather than the action, and was concerned the fans might not approve. He then brought in screenwriter Dean Riesner, who had worked on the scripts of Dirty Harry and Coogan's Bluff, to do revisions. Casting Recurring characters Lieutenant Bressler (Harry Guardino) and Frank DiGiorgio (Mitchum) reprise their roles for the last time in a Dirty Harry film. Bressler was Callahan's boss in the first film of the series; DiGiorgio appeared in the previous two, but dies in this film. A new character, Captain Jerome McKay (Dillman), was introduced as Callahan's superior officer. Dillman played a similar role, Captain Briggs, in Sudden Impact. Albert Popwell also returns as a character in this film, having played the Bank Robber in the first film of the series and Sidney the pimp in Magnum Force. The character of Kate Moore, Harry's female partner, went to Tyne Daly. Daly's casting was initially uncertain, given that she turned down the role three times. She objected to the way her character was treated in parts of the film and showed concern that two members of the police force falling in love on the job was problematic, given that they would be putting their lives in jeopardy by not reaching peak
