Continuity mistake: The length of Edward G. Robinson's necktie rises and falls, often within the same scene.
Continuity mistake: When Lauren Bacall attacks Edward G. Robinson (after he goads her wheelchair-bound father-in-law into attacking him, causing him to fall over), she clearly scratches him on his left cheek. Shortly afterwards, Claire Trevor notices the scratch marks and wonders what happened. The only trouble is, she notices them on his right cheek.
Continuity mistake: During the whole scene with the policeman waking up and confronting Rocko, there are several wide-angle shots of the room. The windows show fairly bright light coming from outside...it must have been a case of clear-day thunder and lightning, I guess.
