Harry Callahan is a tough, streetwise San Francisco cop whom they call Dirty Harry. In this action classic, you'll see why and also why Clint Eastwood's reputation as a premier film star and moviemaker is secure. A rooftop sniper (Andy Robinson) calling himself Scorpio has killed twice and holds the city ransom with the threat of killing again. Harry will nail him, one way or the other, no matter what the "system" prescribes. Filming on location, director Don Siegel made the City by the Bay a vital part of Dirty Harry, a practice continued in its four sequels. Thirty years after its arrival the original remains one of the most gripping police thrillers ever made.
