Great cast and great script, some fine music and some beefy convincing violence. A grown-up noir with all sorts of suggestiveness going on. The hoodlum Richard Conte (Mr Brown) seems surprisingly keen on a woman who has had it with him - I think he only hits her once - unusual in this kind of thing. He also seems to be about to perform a lewd act at one point before the camera cuts away with her seemingly 'giving in' to pleasure - unusual for 1955. Lee van Cleef and Earl Holliman (hard guys 'Fante' and 'Mingo'!) appear, certainly by the end not to be interested in women, but each other - I think you see it in a couple of caresses. Cornel Wilde (Diamond!)is morally culpable because of his usage of loose, dark-haired burlesque girl Helen Stanton as a night-time stand-in for the woman he's nuts over, Mr Brown's blonde-bombshell, the drugged-up high-class Moll (she used to play classical piano), stunning B-movie Grace Kelly lookalike, Jean Wallace. As for the plot, it twists nicely and the photography is fine. Lots of lights shining in eyes and a clever little touch when deaf has-been ex-boss Brian Donlevy loses his hearing-aid. That also gets some original use in another key scene. Donlevy is great too. Probably rewards multiple viewings.
