John Sinclair(1900-1945)

Fields walked off the set of "You Can't Cheat an Honest Man" over what the director felt was a minor disagreement, but when it was clear after two weeks that he was not coming back, to finish the project, nearly one third of the film had to be shot using a double. The double used is unknown. It could have been John Sinclair, who had doubled for him in "Poppy" or David Sharpe who was his stunt double in later films. The double wore a plastic mask and most of the shots were long shots.
