Who is Dirty Harry? Right from the Wikipedia….
Dirty Harry is a 1971 American crime film 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 box office 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.
In 2008, Dirty Harry was selected by Empire Magazine as one of The 500 Greatest Movies of All Time.
