You might think this seems interesting, given its lurid title, cast and setting, but I'm here to assure you that it's not. Like other famous big budget stinkers - Goldcrest's 'Revolution' or Hitchcock's 'Under Capricorn' - the problem was precisely that the script didn't come through a major studio. The latter had a long process of developing stories and scripts and it's rare to find something as bad as this from e.g. MGM or Columbia (though maybe a bit more likely from the Poverty Row producers).
Burt Lancaster produced it - it was his first film as a producer - and wanted a role to show his physicality - which it does - and then didn't apply his mind to the rest. Basically, there's no motivation for anything here; and no plot to speak of. Characters just do what they want at the moment. It's all happenstance, from the opening fight/encounter onwards. Awfully thin unsatisfying stuff, which even a decent director and DP's noir touches can't hide.
Over melodramatic with London portrayed rather gloomily.Dissapointing for a Lancaster film.Newton relishing overacting as a villian & Fontaine rather meek.Unrealistic ending.
