Continuity mistake: At Max's birthday party when Audrey is bending down next to Max, she tells him that his father is sorry for not being there, and tells him to make a wish. As the shots go from Max to his mom and back, Audrey's hair is behind her ear, then her bangs are loose, then behind her ear again, etc.
Continuity mistake: Outside the court at 2:15 when Fletcher is first talking to his son in his cell, the clock has the sun lighting up half its face. When he hangs up, the sun disappears from shining on the clock only to reappear again towards the end of the scene when he is gagging and walking away from his client.
Continuity mistake: When Greta is asking Fletcher about her raise, the clock on the wall behind his desk says either 11:05 or 12:05 (hard to be sure). When he was on the phone with the judge, he said court started in a half hour, but when the courtroom scene starts we focus on the clock showing the time to be 1:30.
