Four Christmases (2008) - 9 mistakes

Continuity: During the scenes at her Mother's house, Kate's hair goes from blonde to REALLY blonde.

Factual error: At the end of the movie, the news reporter should not have been able to go into Kate and Brad's hospital room to surprise them, without any kind of consent from the couple beforehand.

Continuity: At her mother's house, when Kate finishes with the pregnancy test, its position moves on the counter beside her.

Continuity: At Pastor Phil's church, when Kate and Brad are preparing for the play and the baby is handed to Kate, the pamphlet jumps in and out of the baby 's grasp between shots - when his hand is not at his mouth.

Continuity: After Kate is thrown from the jump jump, we see alternate facial shots of Reese and her stunt double before she climbs back in.

Character mistake: In the opening scene where they are at the bar pretending to pick each other up, "Kate" calls "Brad" Vince, which is neither his character in the film, nor the name of the person he's pretending to be in order to pick up Kate (Daphne in that scene).

Continuity: At her mother's house, when Kate is in the bathroom after she changes her clothes, the items in Courtney's baby bag disappear, reappear or change position.

Factual error: When Brad and Kate are in the taxi on the way to the airport, they are shown crossing the Golden Gate Bridge. They supposedly live in the city of San Francisco itself, and therefore should be heading south to the airport. The Golden Gate Bridge is to the north, and is completely in the opposite direction, by about 18 miles.

Continuity: At Paula's house, during the game, when Denver eats the chicken wings they change between shots.
