Factual error: It's very nice that the Kate and Jonas clones came out looking exactly like the originals, but the DNA doesn't contain information about the hair length and exact haircut (and mustache, in Jonas' case) at the time of the replication. They would never come out exactly the same.
Continuity mistake: When the thumbs are in the car driving to the woods, in some shots their thumbs are out of their shirt a lot, but in other shots, they're in there all the way.
Factual error: The fake Rheya tries to kill herself by drinking liquid oxygen. The liquid shown is green, viscous, and foaming and looks a bit like the monster's body fluid in Alien. Liquid oxygen is colorless, non-viscous and doesn't produce sticky bubbles. (01:00:25)
Continuity mistake: In the scene where Justine's husband needs 'help' at the doctor's office, Justine is wearing a flannel shirt and overalls. Then, when she's back at work, she's suddenly wearing a multicolored sweater briefly for one scene (which is what she wears two days later during the day she talks to Holden's parents), then at the end of the day she's suddenly wearing the same flannel shirt and overalls. (00:57:45)
Continuity mistake: At the beginning of the movie she drives off and arrives at her next destination and you see a Florida license plate on the front of the car. Florida only issues a rear tag, and notice the front and rear tags don't match.
Factual error: The train to London that everyone gets on is a French TGV. The TGV doesn't run through the Channel Tunnel, only the Eurostar trains do.
Revealing mistake: When Charlie is writing her letter we can see it through a hidden camera in the pen she is using. By watching the angle on how the camera would be attached to the pen we know that she would have seen the camera. Also her hand would be blocking the camera view, so we shouldn't be able to see anything at all. (00:30:30)
Continuity mistake: When Fowler tells Phuong that Pyle is dead she is leaning back in a chair. First her long hair is hanging down in front, then it moves to the back between shots. (00:06:50)
Revealing mistake: When the two main characters explode and then implode near the end, you can see that some of the debris being sucked in are passing "through" various other objects, revealing they are computer generated.
Other mistake: In the scene where Antwone is in Cmdr. Davenport's office and he is wearing the black, long sleeve shirt and tie, he has mysteriously been promoted from E-1 to E-4. He had never reached that rank anytime in the movie.
Continuity mistake: When Lee is burning her leg with the hot kettle in her bedroom, the way in which the pink towel is wrapped around her head completely changes between shots. (00:08:10)
Continuity mistake: When Virginia has kissed Vanessa she leans her forehead against Vanessa's forehead. When it cuts their heads are away from each other.
Factual error: At the very start of the film the words "Vienna, Austria," appear on a black screen that then fades to a city skyline. The fault is that the city shown is Florence, Italy. Very obvious due to the Duomo, (Cathedral), the tower above the Uffizi Gallery and the Ponte Vecchio, (bridge).
Continuity mistake: During the film's climax, in which the Wolf's wife Serena is on the run, CIA agent Peter Brandt tries to ambush her in an elevator. As he runs up to the elevator, we get a wide shot of him, the people waiting for the elevator, and the up/down indicator lights of the elevator. The down indicator is lit. (The shot pans down from the indicator lights as he runs up.) Cut to Elias briefly, then back to the elevator indicators. This time, neither light is on.
Continuity mistake: On the way to the big robbery, Tarzan shoots a hole in the roof of the car with a shotgun. In the next shot we see the car from above and the roof is intact.
Continuity mistake: When Hart was being introduced to the new barracks, Sgt. Pepper had his chevron and 25th infantry patch on his shoulder, then he didn't, then, he did.
Visible crew/equipment: In the bathroom stall scene when Elvis is examining the hieroglyphics, a mic can be seen in the window reflection when the camera shot is looking out of the stall at Jack the old man.
Factual error: When Alicia goes to the hospital for the first time, the sun is setting directly in front of the window of Erika's room. But then in the morning the sun is rising in front of the same window that it had been setting.
Continuity mistake: In the scene where Alan is showing him how the Thunderpants work, he puts them into a machine to get rid of the stink or whatever it is. It makes a load of noise and just before he takes it out again you see the lights change and he is drumming his fingers just behind them. The very next shot shows him with his hands by his sides.
Continuity mistake: In the scene where Maud and Roland are lying on the bed in the hotel talking about their love problems, Maud moves her head back slightly on the pillow and then keeps it there so her head is about thirty inches away from his. Roland's head doesn't move but in the shot where they are about to kiss each other, their heads are almost touching.
