When Fanny and Eddie go to the club, Fanny points out "Shirley Claire, the famous actress" and the shot is followed by two stock footage inserts from another film, showing a young man talking to a pretty young woman while seated at a table. This footage is actually from the original The Pace That Kills (1928), and the actress shown was the one who played the original Fanny. So essentially, in this scene, Fanny points to herself.

Late in the movie, the cocaine addicted brother gets the money to get his cocaine 'fix', and is next seen in a Chinese opium den having an opium pipe prepared for him. Cocaine and opium are unrelated drugs, and one will not satisfy an addiction to the other.

Opening statement: Among the many evils against which society struggles, one of the most vicious is the traffic in dope . . in every community where the menace developes all the forces which society can mobilize, including social agencies, doctors, law enforcement officials and government band together to stamp it out . . . . . . Without such activity the dope evil would run rampant. Yet it has long been recognized that one other powerful force is necessary before the struggle can be completely successful. That force is an aroused and educated public awareness. It is in the hope of aiding in developing such awareness that this picture has been produced. What happens to Jane Bradford may happen to anyone. There will always be "Jane Bradfords" until you, Mr. Citizen, co-operate with the forces now fighting the dope evil to forever stamp it out in our land. --The Management.
