Continuity mistake: When Daphne first meets Jason, she places two of Milly's business cards on the table and Jason takes one, leaving one remaining. But when Johnny takes a card for himself after talking with Daphne, there are still two business cards on the table. (00:19:30)
Visible crew/equipment: When George drops Lee, Carter and Genevieve off outside the embassy to meet Reynard, right before George tells them he won't be there when they get back, as the camera moves around the car a reflector screen and a crew member can be seen reflected in the side window of the car.

Continuity mistake: Francis' bandages change from shot to shot. Example: When they first leave their compartment on the train to go get a drink, they make their way along an aisle.

(00:05:35)
Continuity mistake: In the opening of the movie, when Rusty and Danny are flying back to visit Rueben, you see them boarding a Gulfstream G200. However, the interior shots actually show them flying in a Gulfstream 5 (probably the one on the ramp next to the G200 when they exit the aircraft).

Continuity mistake: In the study there is a large beige rug, which encompasses most of the room and has furniture on it, that moves farther away from the step up to the doorway as the scenes progress.
Other mistake: Right at the beginning of the movie, when Lewis's real mum picks him up from the box and hugs him, it's no more than three seconds before she hears Lewis from the future slipping on the step. She gets scared and puts baby Lewis back in the box. When Wilbur takes Lewis to meet his mum, near the end of the movie, the time his mum holds the baby is more than twenty five seconds.
Continuity mistake: In the beginning of the movie, Rachel lies down in the shade of a billboard on the side of the road. When they cut to the wide shot the shadow of the billboard is on the opposite side so Rachel is in sunlight. This might have symbolized the passing of time, but in the next shot, when Harlen comes to wake her, she is in the shade again.
Revealing mistake: In the opening scene, the little girl pulls the cake over to her with only a few fingers which is near impossible. When the camera angle shifts and she lets go of the cake, it still wiggles as if she's pulling on it, showing that it's being controlled from the other side, most likely by an off-camera crew member. (00:01:25)

Factual error: When Richard asks Art his opinion of his book, a copy of "Haymarket Scrapbook" is on a shelf. This book was first published in 1986, yet Richard's book will be published in 1981. (01:03:00)
Factual error: Trudie and her family are released from jail because David, being the victim of kidnapping, decided not to press charges. That's not how things work. It's not up to the victim to decide whether or not to press charges. It's up to the prosecutor to decide or not to press charges.
