Continuity mistake: In the beginning of the movie Sylvester Stallone is driving his truck into the driveway of his son's school, you do not see the eagle hood ornament on his truck at this time. But as he parks the truck in front of the school you now see the eagle on the top of the hood.
Continuity mistake: When Michael leaves the Cutlers' mansion he takes a white truck. When he is outside the gates right before he runs a red light you can see the headrests behind him. But when he is on the expressway they've disappeared. Then when he gets to the airport they reappear.
Character mistake: During the movie, Stallone Lincoln Hawk is referred several times as 'Hawks' by other characters (the police officer retrieving him from his cell, as well as his former father-in-law, who should know his real name). Lincoln actually calls himself Hawkes before he crashes the gate.
