Continuity mistake: When Lucille is on the bridge the money falls out of the hat box and hooks onto a small beam. She then puts the hat box on the ground with the lid wide open. After she gets back to safety and the first cop is hassling her, a second cop approaches, he looks down then squats down. When he does we see that the hat box is not wide open, just partially open.
Continuity mistake: After Peejoe gets hit by the rock he begins to fall backwards. In the closer up shot his legs are staggered with his right leg underneath him and his left leg out front. When the camera moves to a wider shot his legs are side by side. A third shot shows his left leg straight out in front of him as he falls. He had also fallen half the way down on the closer up shot before they moved to the wide shot. In the wide shot he was back to being more upright and falling.
Continuity mistake: When Joan leaves the room with the hat box the box is sitting on the bed with the front edge of the box in the center of the overlap of the curtains.

Continuity mistake: When the sheriff has Lucille at the jail she tells him about the horrible things her boyfriend did to her. During the conversation she is rubbing up and down on a bar.
