Other mistake: In the beginning of the film, when they are showing Dre's "growth chart", it shows about 2.5 inches of growth between April 2003 and May 2003, which is not possible. And no, there is nothing in the movie that indicates he has some sort of abnormal condition that causes rapid growth.

Other mistake: When Edwin paralyses Isabelle with poison she almost immediately drops down and loses the ability to speak.

Other mistake: They already stated nobody had TV when the young couple were flirting. Then as the tornado is about to hit the family home Dad rushes to get daughter Sam to go to the basement, and she is playing in front of the TV which appears to be broadcasting the news.

Other mistake: The impression of Robin Hood's hands in cement, made as a child, match the size of his adult hands.
Suggested correction: There were two sets of handprints. The one on the left was that of a child. The one on the right was that of an adult. When Robin reopens the slab, the prints are covered in mud and debris. He runs his hand over the child print then puts his hand in the adult print of his dead father.
Other mistake: In the last scene when Jeep, Charlie, and the baby are driving off, the gearshift of the truck is located in "park". That is located at the topmost point of the gearshift's travel.
