Harold Francis "Dirty Harry" Callahan is a fictional San Francisco Police Department inspector in the films Dirty Harry (1971), Magnum Force (1973), The Enforcer (1976), Sudden Impact (1983), and The Dead Pool (1988). Clint Eastwood plays Callahan in all five films.From his debut in Dirty Harry, Callahan became the template for a new kind of movie cop: a borderline vigilante who doesn't hesitate when crossing professional and ethical boundaries in pursuit of his own vision of justice. The "Dirty Harry" archetype does not shy away from killing, either; all of the Dirty Harry films feature Callahan killing criminals. He justifies such conduct by saying that it "gets results" in cutting down crime. This rationale rarely impresses his superiors, who have threatened Callahan with suspension and firing many times.
