Crabbe was lousy in this. His acting was shoddy at best. He must have spent a grand total of 15 minutes reading his lines before the shoot and the kid sounded way to coached. The roundhouse punch he faked would get any fighter killed just trying it. The rest of the cast was fine except Rita, but the lead wasn't in the least convincing nor was the kid..Rita’s performance was about as convincing as my dog playing the part of my goldfish with snow tires as fins .Highly disappointing for Buster Crabbe.

The actor who plays Biff, is Glenn Strange, who played Sam the bartender on Gunsmoke! for many years, in which he uttered lines nothing more challenging than "Yes, Miss Kitty" - Here he does a fairly good job in his role as Crabbe's best friend - The ring announcer for the climatic fight scene in the film is Jack Bailey, the ubiquitous host of "Queen For A Day" in the 1950s.

If you can get past the oh-so-annoying child actor, you'll find this a predictable but enjoyable account of a prizefighter who, spoiled by success, loses sight of what's really important. Buster Crabbe's a bit too old for this part but it's still good to see him with his shirt off, and his two leading ladies -- when they're not ogling his bare chest -- sometimes engage in dialog which has surprising flashes of wit.

this movie left me with a smile very well done
