Dirty Harry Is At It AgainSensitive to outcries of police brutality, the superiors of San Francisco Detective Harry Callahan have sent him on an out-of-town assignment until things cool down. But wherever Harry goes, things just get hotter.Clint Eastwood hits the mark again in Sudden Impact. Callahan's older, dirtier and the world hasn't gotten better. Which means this fourth Dirty Harry movie (which Eastwood also directs) is explosively exciting, as Callahan tracks a traumatized rape victim (Sondra Locke) coldly gunning down her bygone attackers. Through the five Callahan films, the lawman always struck a powerful chord. But Sudden Impact is particularly potent, fueled by the line that became a national catchphrase: "Go ahead. Make my day."
