Continuity mistake: Harold Hall and Mary Sears are sitting in a car on the movie studio lot. A stagehand raps on the car door and tells Mary they're ready to start filming. In a close-up, she opens the door and steps out of the car. The following long shot shows her opening the door and stepping out of the car again.
Continuity mistake: Vance, smoking a cigarette, warns Harold to stay away from Vance's girlfriend and drops his cigarette in Harold's coat pocket. A close-up shows a lot of smoke coming from the pocket, but there is a noticeable jump between the two scenes and Harold is in a slightly different position.
Continuity mistake: When Harold climbs in the window of his house, his car rolls away to the right. After hearing the crash, he runs back to the window and looks out - to the right, where he sees the wreck. But that's the wrong direction. From inside the house, the wreck should be to the left.
