John Wayne made Brannigan a Chicago cop picture instead of a Western, and the film now reads like a late-career detour through the crime thriller lane. Douglas Hickox gave him a role built around pursuit, friction, and a city far from the range. For Wayne, that shift put his tough-guy persona into a different market.
Chicago to London
Wayne plays the eponymous Chicago cop, and Brannigan sends him to London to bring back a mobster. The setup gives the film its Dirty Harry-style shape: a blunt police lead dropped into a system that does not bend around him.
Richard Attenborough plays Commander Charles Swann, and his conflict with Brannigan gives the movie its clearest pressure point. The clash is not about scale or spectacle; it is about method, control, and what happens when a hard-edged detective style meets a different chain of command.
Frank Sinatra and Richard Attenborough
Wayne had already turned down Dirty Harry because Frank Sinatra had been offered the role of Harry Callahan first. That choice matters because it shows how close his late-career cop work came to the same lane Clint Eastwood later occupied, even though Wayne and Frank Sinatra had been long-term enemies.
Brannigan sits next to McQ, another Wayne cop movie in which he plays a detective investigating his partner’s assassination and uncovering corruption in the force. Together, the two films show him moving through the same rough wheelhouse as Dirty Harry rather than staying in the Western space that defined most of his career.
1979 and Wayne
McQ and Brannigan were among Wayne’s final roles before he died in 1979. That makes the film less of a side note than it first appears: it is one of the clearest examples of John Wayne using his last screen years to test an action format that audiences usually associate with Clint Eastwood and Harry Callahan, not The Duke.
