Gossip Friday: Not a Knockout

From June 1936:

The famous knockout blow that Clark Gable delivered to his skilled opponent in the prizefight scene for “Cain and Mabel” will be retained in the picture, but will not appear as a knockout. Warners wanted to use it as the end of the 15-round bout in the story, in which Clark co-stars with Marion Davies, but the camera caught the “Round 1” marker above the ring, and there is no way to keep this from showing. As a result, the scenes will appear as a knockdown, and another way will be figured for Gable to score a kayo at the finish of the fight.
