Dirty Harry

''Dirty Harry'' is a 1971 American action-thriller film produced and directed by Don Siegel, the first in the ''Dirty Harry'' series. Clint Eastwood plays the title role, in his first appearance as San Francisco Police Department (SFPD) Inspector "Dirty" Harry Callahan. The film drew upon the real-life case of the Zodiac Killer as the Callahan character seeks out a similar vicious psychopath.

''Dirty Harry'' was a critical and commercial success and set the style for a whole genre of police films. It was followed by four sequels: ''Magnum Force'' in 1973, ''The Enforcer'' in 1976, ''Sudden Impact'' in 1983, and ''The Dead Pool'' in 1988.

In 2012, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, and aesthetically significant". Provided by Wikipedia
