Factual error: There's a scene when Barbara Stanwyck hides behind an open door to avoid beeing seen by Edward G.Robinson leaving Fred MacMurray`s apartment. To make this possible the apartment door opens outside into the corridor, which is an elegant solution for this situation in the movie. But in the real world no apartment door would open by swinging into the corridor because this would give a visitor standing there a punch on the nose when the resident opens the door.
Revealing mistake: Several pieces of furniture, including a large sofa, fall over before the suitcase bomb actually explodes.
Continuity mistake: Dick Powell puts his gun in his left trenchcoat pocket and then 2 minutes later takes the same gun out of his right pocket.
