In the first shot of Tim Hayden (John Garfield), he is seen typing on his typewriter. Initially, and briefly, the carriage of the typewriter goes backwards then reverses direction - as if the film was run backwards in editing for a second or so for no apparent reason.
When Bull is fleeing in the little speedboat, he fires seven shots from his snub-nose revolver.
Bull is seen playing with one of his large dogs in his office. The dogs bark every time a stranger appears and spring at him. Yet, when John Garfield enters a minute or two later, the dogs are neither seen nor heard.
