Continuity mistake: Nick & Holly are having lunch outside their trailer with their friends & kids. One of the kids throws jelly at Nick Cage and hits him in the head, and a piece of jelly with a cherry in it falls on his plate. The camera cuts away as Holly and her friend are talking about Paediatricians. Cut back to Cage and the jelly is gone from his plate. Back to Holly then back to Cage shows the jelly is back!
Revealing mistake: As Hi is racing after the baby, a close-up of his tired face driving the brown Caprice shows the gear selector is in "Park".
