This is the wrestling noir that Barton Fink did not write in 1950. The director, Jules Dassin, also directed the later Rififi, but the real attraction is (of course) Gene Tierney. Strangely her role is tiny and she is completely disempowered; a big part of her charm in e.g. Laura is that her character (and not just her looks) overwhelms men. She is criminally wasted here.
The setting is London, the East End, the underworld, and the plot fails to find much traction. Richard Widmark in the lead left me completely cold, all Jim Carrey-ish in his puppy-dog ingratiation without the humour or whatever it is that Carrey has.
