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: When Lucille sees her children through the prison window you see a tuft of grass outside. Seen from outside it isn't there. (01:20:50)
Revealing mistake: When Lucille sees her children through the prison window the bars must have been copied in later. In slow motion you see that they are transparent. (01:20:50)
