During the fight in the photographer's studio, the stunt doubles' timing was off. Mike Tracy is knocked onto the mat by Mike Jamison, who then tries to jump onto Tracy. But although Tracy rolls out of the way before Jamison begins his jump, Jamison jumps onto the mat anyway.

The day after the fight in the photographer's studio, the newspaper has a picture of the fight in progress, which shows all the participants including the unconscious photographer. A press photographer would not have been able to arrive at the scene in time to take such a photo.
