Dirty Harry is a 1971 American crime thriller produced and directed by Don Siegel, the first in the Dirty Harry series. Clint Eastwood plays the title role, in his first outing as San Francisco Police Department Inspector "Dirty" Harry Callahan. Dirty Harry was a critical and commercial success and set the style for a whole genre of police films. The film was followed by four sequels: Magnum Force in 1973, The Enforcer in 1976, Sudden Impact in 1983 (directed by Eastwood himself), and The Dead Pool in 1988. A sadistic serial killer calling himself "Scorpio" (Andy Robinson) murders a young woman in a San Francisco swimming pool, using a high-powered rifle from a nearby rooftop. SFPD Inspector Harry Callahan (Clint Eastwood) finds a ransom message demanding the city pay him $100,000. Scorpio also promises that for each day that the city refuses his demand, he will commit a murder, and his next victim will be "a Catholic priest or a nigger". The chief of police and the Mayor (John Vernon) assign the inspector to the case.
