Continuity mistake: Upon learning that a friend is about to be married to a wealthy man who is still married to his first wife, Harold races to the man's mansion to halt the wedding. Driving a wagon pulled by two horses, he passes the Western Costume Company which was then at 7th and Figueroa in Los Angeles. After passing through a series of tunnels on the road that is now part of the Harbor Freeway, Harold again goes past the Western Costume Company.
Continuity mistake: Harold takes a bottle of chloroform away from his young nephew and puts it in his pocket. The label says "Chloroform, 2% alcohol." Twice at dinner, Harold looks at the bottle and a close-up is shown. In the second close-up the "2% alcohol" is missing from the label.
