Sudden Impact

Sudden Impact is a 1983 American action film and the fourth film in the Dirty Harry series, directed by Clint Eastwood making it the only Dirty Harry film to be directed by Eastwood himself, and starring Eastwood and Sondra Locke. The film is notable for the catchphrase, Go ahead, make my day, which is uttered by Clint Eastwoods character in the beginning of the film. That phrase, although in its Italian localization Coraggio... fatti ammazzare come on, let me kill you, was also chosen as title for the Italian version of the film.

Meanwhile, San Francisco Police Department Homicide Inspector Harry Callahan is frustrated when a judge yet again dismisses a case due to unreasonable search and seizure. Later, at his favorite diner, the inspector interrupts a robbery and kills most of the criminals. When the surviving robber takes a hostage, Callahan targets the man with his .44 Magnum and challenges him to Go ahead, make my day. The criminal surrenders. Callahan later causes powerful crime lord Threlkis to suffer a fatal heart attack at his granddaughters wedding dinner.Lieutenant Donnelly and other angry superior officers call Callahan in. They cannot fire or suspend the notorious inspector because, as the police commissioner admits, his unconventional methods ... get results, albeit with tremendous physical destruction and bad publicity for the department. They instead order him to take a vacation, which Callahan spends target shooting with his .44 AutoMag and shotgunarmed partner Horace. But Callahans relaxation is shortlived, as four of Threlkiss hitmen attack him. The inspector dispatches three, and the other narrowly escapes. The suspect from the dismissed case and his friends also attack, throwing two Molotov cocktails into Callahans car. He retrieves one of the undetonated bombs and throws it at the attackers car, causing the men to swerve into the bay with fatal consequences. Donnelly immediately sends the inspector to San Paulo to investigate the murder of the man Spencer killed. While the victim is from there, the assignment is also to protect both Callahan and civilians. As Donnelly notes, people have a nasty habit of getting dead around you. ........
