Jules Dassin was one of the talented American directors who came to Europe after WWII to flee McCarthyism. And the themes of (breathless) escape and absence of law are central to his UK debut. Richard Widmark plays a no-hope hustler living on stolen time, who spends his days on the run through a noirish London prowled by bigger, more savage beasts.
When he tries to break into the lucrative wrestling game, he calamitously provokes the Mr Big (Herbert Lom) who runs the racket in the capital. This is an underworld without police, where everyone is on the make, where the criminals bring down each other and only the strongest and most ruthless survive.
It is a cleaned up version of Gerald Kersch's incredibly pessimistic and fatalistic novel; the prostitutes become night club hostesses, etc. Dassin made the socialist film he never could in Hollywood and portrays London as a Darwinist concrete jungle, never more potently than in an astonishingly brutal wrestling scene.
Widmark is indelibly sleazy as the doomed wannabe. The ensemble support cast is all brilliant apart from the misplaced glamour of Gene Tierney. Googie Withers is always worth seeing. And it looks a knockout. Maybe this is the only UK noir that fully stands up to Hollywood on their own terms.
