Continuity: After Marcus breaks McTeague's pipe and throws a knife at him, men pull McTeague's tie off as they hold him back. The tie is back in place a moment later as McTeague rushes out of the saloon.
Anachronisms: Although all the principals have costumes and hairstyles appropriate for around 1900, outside the theater the other patrons seem to be in modern (1923) dress. A recent-model automobile is even visible in the last exterior shot of the theater.
