You’ve got to ask yourself a question. ‘Do I feel lucky?’ Well, do ya, punk? When a serial killer calling himself Scorpio menaces women in San Francisco cop ‘Dirty’ Harry Callahan (Clint Eastwood) is assigned to track him down. He’s involved in a cat and mouse chase that sees him racing all over the city in pursuit even dragging a school bus with children into the fray and bringing him into disrepute by questioning suspects’ Escobedo and Miranda rights. This starts by honouring the institution of policing and ends very firmly on a note of critique – with a move by Harry that is replicated by Keanu Reeves in Point Break twenty years later (albeit Harry gets his man). This starts in such an astonishing fashion, with the camera at the killer’s shoulder when he takes aim with a sniper rifle at a woman swimming in a rooftop pool: it sutures you directly into his point of view and makes you question everything you see. There is an undertow of satire (and a string of murders) that secures your sympathy for Harry’s unorthodox approach. The story by Harry Julian Fink and R. M. Fink was vaguely based on the Zodiac killer terrorising young women at the time (and later the subject of another brilliant film) and was rewritten by John Milius and Dean Riesner (and Terrence Malick did an early draft), and the end result is tight as a bullet casing. Milius said it’s obvious which parts of the screenplay were his – because for him Harry is just like the killer but with a police badge. It’s directed in such a muscular way by Don Siegel (who had just made The Beguiled with Eastwood) and characterised so indelibly by Eastwood there is only one word to encapsulate it – iconic. Much imitated (even with four sequels of its own) but never equalled, with a moody empathetic score by Lalo Schifrin. What’s weird is that the killer was played by unknown actor and pacifist Andy Robinson – who replaced war hero Audie Murphy following the star’s death in a plane crash before he signed on the dotted line.
