Other mistake: In the end credits, the character played by Tina Sloan is listed as "Stationary Saleswoman". The correct spelling of this character should be "Stationery Saleswoman", as she sells stationery. She doesn't sell while standing in one spot.
Revealing mistake: In the scene at the beginning of the film when the bus enters the village, you can see that the road signs are on the left side of the road (not facing the bus) and the continous line that separates the two ways is on the exit of the curve, not before the curve. This is because the action of the movie is set to happen in England but that scene was filmed in Romania, a country with right-hand traffic. (00:03:20)
Factual error: When Richard asks Art his opinion of his book, a copy of "Haymarket Scrapbook" is on a shelf. This book was first published in 1986, yet Richard's book will be published in 1981. (01:03:00)
Continuity mistake: When Abe is being tortured by the Harpies, at one point, you can see that his body is covered with cuts and his blue-colored blood. The blood then disappears and reappears in subsequent shots.
Continuity mistake: When Doomsday slams Superman down into the subway, the hole they make in the street is right in the middle of a crossing. But a minute later in the film as civilians are walking up to the hole, there are no lines anywhere around it. Moments later after Jimmy takes a picture of the hole, the shot cuts to a far angle and now the hole is next to the crosswalk lines, and in that shot the stairway entrance to the subway station also vanishes. The road also becomes much wider with more lanes, and the red truck turns around. (00:22:40 - 00:23:25)
Factual error: Cranes are shown crossing the Himalayas, then a reference is made that the snow melts giving life to the rivers in Asia, but the footage shown is of the Angel Falls in the Amazon Jungle in Venezuela where there is no snow. (00:50:40)
Factual error: After the little girl is taken they play audio of the mother on the phone with 911, the operator says they can't do anything for 24 hours. Police do not wait 24 hours to look for a missing person, especially a child.
Factual error: Trudie and her family are released from jail because David, being the victim of kidnapping, decided not to press charges. That's not how things work. It's not up to the victim to decide whether or not to press charges. It's up to the prosecutor to decide or not to press charges.
Continuity mistake: When being shot at by the angry waiter, the right hand door mirror was hit by the rifle shot. A few seconds later a view shows only a very minor hole in the glass, and no damage to the rest of the mirror. Surely a rifle shot would have caused more damage to plastic and chrome trim, almost surely passing right through. (00:30:20)
Revealing mistake: When they blow up the whale, it is obvious it is just a large prop, as there isn't much blood or tissue flying through the air. You can tell by comparing it to the famous news reel online that shows what happened when the exact same thing happened in real life.
Continuity mistake: While Susan and Charlie are passing notes towards the beginning of the film, her cell phone (a Virgin Mobile endorsement plug) continues to flip from a lying down position to a propped up position on her desk between shots throughout the scene.
Visible crew/equipment: When the ambulance is about to crash into the tanker, right before and during the crash a camera mounted (painted white) on top of the cab is seen.
Continuity mistake: In the beginning scene at Vincent's trailer, Errol is looking through the cupboards as he questions Vincent. He comes across an adult magazine, and flips open to a page. He flips another page or two over, and the exact same picture is shown as the first picture he opened to initially.
Continuity mistake: When Chris is talking with Luvlee, and Gary has just gone back to the bedroom with a beer, Chris' head changes position without enough time for him to do it, while the camera switches back and forth from Chris to Luvlee.
Other mistake: There's a scene at the end of the movie where Annie is sitting looking through some graduate school brochures, and her boyfriend Hayden comes over and hands her a letter from the "5th Avenue Mom" she used to work for. She says she can't read it so he offers to read it to her. The camera shows a close-up of the letter as Hayden starts to read. In the letter it's written that it's been "some time" since we've spoken, but he reads it as "several months."
Continuity mistake: When Nikki and Kat are sitting on the floor in a secluded part of the library, there is a single book lying flat on the bottom shelf in front of them, with the binding facing out. In the next shot the book has changed position.
Factual error: Contrary to popular belief, a person won't freeze immediately in outer space, as depicted in the movie. Space may be cold, but it's also a great insulator and the biggest problem for astronauts is dissipating the heat generated in their bodies.
Factual error: In the beginning when Anwar is in Cape Town, South Africa, according to the shadows cast by the men in Anwar's party, it's about 1 pm. He makes a call to Isabella in Chicago, United States when he apologizes for not calling her earlier. Cape Town is 8 hours ahead of Chicago, it would have been pitch dark in Chicago at that time but Isabella is outside in the midday sun playing soccer with Jeremy.
Continuity mistake: There's a scene in Kate's restaurant kitchen where Nick asks Zoe to hold the big bowl of spaghetti he had been eating, and she starts eating it. At one point there's a piece of basil hanging off the edge of the bowl and when the camera cuts back to her, it's gone.
Factual error: When Tom shocks Angela with a stun gun, she gets knocked out. That's impossible. Stun guns don't knock you out. Stun guns don't cause unconsciousness.
