Continuity mistake: During the car chase, the wound on John's cheek changes colour between shots. (01:21:55)
Continuity mistake: During the car chase on the freeway, Jane forces one of the pursuing cars off the road by driving, with it, through those large barrels of water near freeway exits. Water cascades over the cars; one interior shot shows that it's virtually impossible to see through the windscreen. Yet in the next shot, a few seconds later, all the cars are completely dry.
Other mistake: After the Smith's house blows up both John and Jane's white shirt's are really really dirty but when they're driving in the stolen van their shirts are bleach white again except for the blood stains.
Continuity mistake: When John and Jane open the door to greet the neighbours after the fight, Jane is on John's right side under his arm. In the next clip she's on his left side.
Continuity mistake: When Pitt is chasing after Jolie, he crashes through a fence and fires his gun, hitting the car's windshield. To the left of where Pitt is, you'll notice that there's one rail missing in the middle. When he climbs through the fence to the street, the fence rail has returned, and the hole left by Pitt is now slightly wider, just enough for him to climb through. (00:45:40)
Continuity mistake: During the beginning scenes of the car chase, the golf bag moves in the trunk. In the first clip there are some bags in front of it, but in the next it's all the way in the back of the trunk. (01:21:35)
Continuity mistake: During the car chase you see several clips where the car's sides are bumped and have bullet holes, but also several clips where the cars sides are in pristine condition. (01:23:15)
Continuity mistake: When Jane and John are fighting in their house, John runs by and knocks the teapot over. He fumbles with it then grabs it with the top facing him. In the next shot, the top is facing away from him, so that it may proceed to fall off.
Continuity mistake: When Jane enters her house with the girls, the front door has a chain door lock. When John enters with the neighbor there is no chain door lock. (00:50:15 - 00:51:45)
Visible crew/equipment: When John and Jane first meet in Bogota, you can see the set lights reflected in John's glasses.
Continuity mistake: After John races Jane home and goes in through the back, he breaks a pane of glass square with his elbow to unlock the door. About 1 second later, the break in the glass is different and no sound is heard of more glass falling off to change the shape.
Continuity mistake: When they are both fighting each other in their house Brad throws Angelina against a wall and you can see that she is a stunt double.
Continuity mistake: After Jane and John have finished destroying there own house. Jane goes to the fridge to get something to drink revealing one of Jolie's real tattoos on her arm that Jane does not have in any other shots.
Revealing mistake: When Jane catches the wine bottle that John drops, you can see her holding a second bottle in her hand before he drops his.
Suggested correction: You can assume that's how they filmed it, but nothing seen in that shot suggests that there were two bottles, since Jane's arm is never even in the frame before John drops the bottle.
Even watching in slow motion I couldn't see a 2nd bottle. In real life, catching the bottle wouldn't be that hard if you knew when it was going to be dropped. Maybe the people seeing two bottles are confusing the gap between Brad's legs as the bottle. And using 2 bottles doesn't even make sense. If Angelina couldn't catch it in real life, it would be way easier to do a jump cut than some cheap magic trick.
You can definitely see her holding a bottle. It is weird how it disappears but there is definitely an appearance that she is holding a bottle right before he drops it.
Continuity mistake: During the fight in the house John gets two cuts in the face. But even seconds after the fight ends, the cuts no longer bleed, and the blood is dry.
Continuity mistake: John shoots Jane's car, but in the later shots of the film, the holes of the bullets are gone.
Continuity mistake: In the scenes prior to the Smith's house being blown up, when Jane is wearing only a white shirt, she is not wearing a watch. In the scene just after their house is blown up, where they are lying in the yard, Jane is wearing a watch.
Continuity mistake: When John comes home after discovering Jane's identity his neighbour says his car is on the sidewalk. But in the next shot it is not.
Continuity mistake: When John and Jane are having breakfast on the floor after their huge fight, John eats something out of a tall silver container. He then puts it on the floor next to Jane, who picks it up and sticks a spoon in to get some of what's in there. It then cuts to a closer shot of the pair, and Jane is chewing on the food and putting the container down, even though she didn't put it in her mouth.
Revealing mistake: When Pitt is on the roof of Jolie's car, he breaks the window in order to get into the car. First off, when played in slow motion, the feet never do touch the glass before it explodes. Second, all newer vehicles have shatter proof glass both on the windshield and the side windows. In real life the glass would have just cracked, not blown out as it did in the film. (00:46:25)
