I saw this film about two weeks ago on AMC. It was in the morning so there was no tag by Bob Osborne when it ended and since I did not catch the very beginning, I did not see the credits. I saw the boxing match and it was BRUTAL. What a fighter goes through was never conveyed more clearly and more succinctly. I remember Frank Silvera from other films (and it was his name that I looked up to find here at IMD. The actors were unknown and the two leads were not that convincing but the story was riveting. I was prepared for an ending suitable to the type of dark film it had been up to that point. I really liked the ending that was revealed. I came here to read comments on this little known film and was totally surprised to learn that Stanley Kubrick directed it. He told a story in a lean, sparse way that was different from the way he told later films but his genius was showing here. Bravo to all connected with this little gem!
