Continuity mistake: At the museum, John and Diana are talking at a table while the kids are playing together. There is an empty glass with a blue straw in front of John. Sometimes, the straw points away from him, sometimes it points towards him.
Suggested correction: The straw never points in the different directions throughout the scene, it alwaysstands there almost the same way.
Continuity mistake: Early in the film, Nicholas Cage is hitting the bottle. After pouring one or two drinks, he starts to pour another, nearly fills his glass, then spills it. Although the bottle is about half-empty at this point, the next time it is shown standing on a table, there is only a small amount remaining at the bottom.
Suggested correction: There's no indication how much drink is in the bottle after he spills it. There's the correct amount of drink in every point of the scene.
Continuity mistake: When Ms. Thomas is showing them the time capsule, she pulls it out of a box. The box is on the floor when the capsule is put on the desk, and it is plain to see that the capsule would not have been able to fit in the box that is shown.
Suggested correction: The capsule is laying in the box on the side. It's totally the same box in which the capsule was from the start, and there's no reason for the filmmakers to change it at all, it's always the right size to contain the capsule.
Other mistake: He says his wife died in a hotel fire at 4 am, and then says he was blowing leaves when she died. Who blows leaves at 4 in the morning?
Suggested correction: His wife died at 4 am in Phoenix, Arizona, while he was in Boston, Massachusetts.
Revealing mistake: In the scene where John first discovers the patterns of numbers, he writes all of the numbers on his whiteboard. He circles the numbers he finds online with a colored marker. When he circles the number 2708 with the blue marker, he passes over the 8 with the marker, but the original black 8 and part of the 0 appears on top of the blue, showing that it was done using some overlay technique. This same effect is shown several times including when the blue and red pens mix but are still behind the black. (00:24:55)
Suggested correction: Black marker is never on the top of the blue, blue marker is simply transparent, so you can see black marker through it.
Continuity mistake: In the scene where there is heavy traffic on the road (before the plane crash), John gets out of his car to see what's going on. As he's making his way to the front, he passes a black pick-up truck. The camera angle changes, and you can see John pass the same truck again.
Suggested correction: He never passes a black pick-up truck, the only minor flaw is he is shown a little further in the next shot from that truck, than he was in the previous shot.
