Continuity mistake: After Mike punches Billy and pushes him down onto the bar, Billy stands up and shakes the popcorn from his face. The camera angle changes, and now Billy has more popcorn stuck to his face than he ever had before. (00:23:45)
Character mistake: Amanda's lawyer says several times she'll go to the gas chamber if found guilty - once to her, once to the prosecutor and once to the jury. Oklahoma doesn't use, and never has used, the gas chamber for executions. (00:15:00 - 01:16:00)
Factual error: Amanda gets married when she is either 13 or 14. The legal age in Oklahoma is 16, and there's nothing to suggest she lied about her age.
