Continuity mistake: When Jane has just found out she had been accepted into the school soccer team it's clear that on the soccer list it shows Jane is 9 years old, but when her moms speaks to her a minute later when Jane starts to worry about getting into college, Amy states that Jane is 12 years old.

Other mistake: When the children arrive in Blackpool, Emma tells Jake that loop entrances can be anywhere and that "the one in London is in a subway tunnel", but on the map of all the loops they were viewing previously inside the boat, there was no marking of a loop in London.
Continuity mistake: While travelling with the novelties salesman, a passing car's occupants yell about the bag of groceries on top of the car. As the camera faces the salesman's car, he puts up the window advertising the fake bag gag. As the camera faces out towards the passing car, the window goes up again. Later, a truck passes by, and the salesman does the same thing, but the message is now in Spanish, without the man stopping to change it. A moment later, the window advertisement (seen from inside) appears to be in English during the same scene.
Factual error: McVay gives the order to cease zigzagging, full speed ahead, but the Japanese sub commander gives the target speed of 12 knots for the torpedo solution. The Indianapolis was capable of a speed in excess of 30 knots.
Factual error: A few scenes in the movie show Roman cavalrymen using stirrups, which were not used by the Romans until several centuries later.
Continuity mistake: At the beginning of the movie, there is a scene where Rebecca's phone is ringing, and it wakes her up. She grabs the cell off the night stand. She has red nail polish on. When she puts the phone back down on the night stand, her nails are natural, not polished.

Plot hole: The system providing oxygen can only be accessed by someone slim. Therefore John Goodman built the bunker with him unable to access the key facility that provides oxygen in his bunker. Yet he must have been able to go and get Britney when she went to that area?
Suggested correction: It's not a plot hole because he said in the film, the normal hatch to the air filtration was blocked by something that fell on top so they couldn't get through that way.
Other mistake: When Helen Mirren and Will Smith are standing on the subway platform and the scene cuts away to view them from the other side, we see them through the windows of a passing train. Dame Helen suddenly gets out of character and hastily answers her cell phone. She was playing a "spirit" on behalf of Will - not someone who'd have a phone. (01:04:00)
Factual error: The main character is being wooed by Lockheed - an aircraft company, whose representative then gives him gifts for his kids - one of which is a desk model of an aircraft, however it is of an aircraft produced by one of Lockheed's competitors - Grumman, which would be akin to a GM rep giving a toy Ford Mustang as a gift. Both companies continue to remain competitors as Lockheed-Martin and Northrop-Grumman since the government vetoed a proposed merger back in 1998, and at no time have the two companies collaborated on a major project.
Factual error: The present day "Grimsby" train station shows electric wires and trains. The real Grimsby only has diesel ones.

Continuity mistake: The wounds that Juda got on his face from the fall from the horse at the beginning of the film, disappear the very same day.
Continuity mistake: When they are in the big hall he goes to demonstrate that he can shoot. He shoots 5 arrows. When you see the arrows hit the bowl only three hit. (00:32:00)
Sometimes he shoots 2 at a time. He does shoot 3 times, but he shoots five arrows.
The correction is valid. He never shoots 2 arrows at once. You may need to watch in slow motion if you can't see what happened. He grabs 3 arrows with his right hand and keeps them in his hand as he shoots 1 arrow at a time. This is probably most obvious on the 2nd shot where you see the 2 arrows in the bow, but when he releases his hand, you see one arrow still in his right hand and 1 arrow leaving the bow.
He starts holding all 3 arrows, shoots 1, reloads holding 2, shoots 1, then reloads and shoots the last arrow.
Continuity mistake: A group of people are in the copying room taking turns taking pictures of their butts on the copier. When one of them sits on the glass part of the copier, the glass part breaks. When he gets up, it's not broken.
Other mistake: During the climax, when Junior reactivates the baby manufacturing machine, the first baby to emerge from the machine is naked. The machine's hands diaper this baby. However, when the other babies emerge from the machine they're already wearing diapers. (01:15:45 - 01:16:25)
