Continuity mistake: When Dave is shot by Mindy while training, there are two bullet holes in his jacket when he has only been shot once at that point.
Character mistake: In Pitch Black they established the system they crashed in (M-344/G) had 3 stars. Jack stated it when the 2nd sunrise started, and the solar system model also had 3 stars. In this film when Boss Johns starts asking about M-344/G he says it is "a backwater system with 2 suns and 1 habitable planet."
Factual error: When Braniac's robot probe enters the atmosphere over Arizona, fighter jets attempt to shoot it down by hitting it with missiles. The pod is still going fast enough to be on fire from reentry. A missile could not have caught up to an object going that fast. (00:11:30)
Continuity mistake: Young Dan and Jo are fighting over their meal. The position of the tray on the table changes several times, most noticeably when Dan leaps off the table. Moreover, when he returns to it after he jumped off the bed, the tray is empty minus a little red berry, but it still had rice and other food on it earlier. (00:18:30)
Audio problem: When Tony is telling Pepper about what happened to Rhodey, there is one shot of the side of Tony, slightly to a back angle where he is talking. His jaw does not move at all while speaking during that shot. (00:27:10)
Character mistake: At the party, Fred is supposed to make a bbq, feeding about 50 people. But once he's got the fire going, he puts two lonely pieces of hamburger meat on top, to cook - only two.
Revealing mistake: When Tanya has just died, her face goes still and she stops breathing, but you can still see her pulse beating in her neck.
Continuity mistake: When The Rock is putting early in the movie he is on the phone, when the shot comes back to the room the putting green is missing. (00:01:50)
Factual error: This film takes place in the north eastern USA. During the beautiful scene with the large black bird soaring above, they added a close up of an Andean Condor. The Andean Condor only lives in South America; Peru, Argentina, Chile, etc.
Continuity mistake: Ari during the break from the party begins her seductive scheme; posing as a waitress at this guy's own engagement party, she approaches him while he is -for some reason - in the parking lot, makes him smoke a joint for the first time in front of his car, and kisses him - apparently all of this is super easy, barely an inconvenience. When she touches his face, she lowers her fingers from the chin at least 3 times in separate shots when she is whispering things to him. (00:11:50)
Factual error: It was very nice of the East Anglian Transport Museum at Chappel and Wakes Colne to provide a train for the coder to go home in, and come in to work. The station is even in Suffolk; but of the two lines through the station, one is used by public trains, and the other by historic preserved trains. When the coder gets off her morning train, it is seen passing across points from the museum platform line into the railway museum, rather than continuing up the line to Sudbury, as a public train would. Appropriately, the train is a heritage DMU - a museum exhibit which has not been used on the main line for at least 25 years. So that's three reasons why she's not on a train which actually goes anywhere.
Revealing mistake: Not bad digital effects for a combination "Predator" and "Jurassic Park" monster movie, except that the dinosaurs don't cast shadows about half the time.
Factual error: When the protagonist is looking up the fingerprint (or fingertip...) data in the computer, he gets a match for a New York State Driver license. The document is a clear fake, with no document number (which in 2008 was on the front) and a 10 digits client ID number instead of 9 digits. (00:04:00)
Continuity mistake: Max is wearing a suit jacket while he is beating a young woman. He throws her against a dresser and then when he goes to pick her up he is in shirtsleeves.
Continuity mistake: Cereza takes a bath. She does not have glasses in the bath tub. Thrice during this two minute period, the film shows her glasses to be in the hotel room, on her bed, along with her dress. And yet, when Cereza comes back to the room, she has glasses on. (00:38:00 - 00:40:00)
Factual error: Near the end, Zoe and Trey battle to the death, Zoe armed with a tomahawk and a knife, Trey armed with a Husqvarna chainsaw. During the battle, Zoe manages to amputate Trey's right hand, with which he was gripping the chainsaw's safety release and trigger (as his left hand gripped the support handle). Bellowing in pain, Trey continues swinging the chainsaw by its support handle with his left hand. Lo and behold, the chainsaw is somehow, miraculously, still revving in-and-out, which is only possible if the safety release is continuously depressed with the palm of the right hand as the fingers rhythmically flex to squeeze the trigger. Of course, with all major tendons in the wrist severed, an amputated hand cannot grip or flex or squeeze anything.
Visible crew/equipment: When the old guy (Mr Sites?) is leaving the gas station and talking on his phone you can briefly see a large shadow of the boom microphone on the wall/pillar, left side of the screen. (00:55:04)
Other mistake: Throughout the film, you can frequently see many people's faces blurred, phone numbers blurred, store-fronts blurred, etc. This is because the production could not afford the rights to show these people, places and things, and simply blurred them out.
Continuity mistake: As El Camaleon pulls the Cuba Gooding Jr. face off, there's an unshaven neck with a tattoo visible under it. After the cut, Lady Gaga's face (also presumably unshaven admittedly, but not visibly so) comes to light under a mask of visibly lighter skin tone. (00:45:05)
Continuity mistake: The movie opens with a man walking with a dog by a body of water. He is holding the leash with his left hand and the dog is by his left side. Cut to the next shot taken from across the water, the leash is now in his right hand and the dog is on his right. (00:00:20)
