Charles Vidor started directing this movie but was fired after a few days of shooting and replaced by Charles Brabin.
It took Boris Karloff 2.5 hours every morning to apply makeup for this role.
As originally scripted, during the torture sequence, it was planned to have Von Berg (Jean Hersholt) suspended over the crocodile pit and Neyland Smith (Lewis Stone) about to be impaled by the walls of spikes. This was reversed when, for reasons unknown, it was thought that a fat captive would make more sense being impaled than a thin one.
MGM once considered Clark Gable for the part later played by Charles Starrett.
