Other mistake: When Meg Ryan is getting out of her black Lexus in front of her house (about 8 minutes into the movie), you can see that it is late in the afternoon by the shadows of the bushes and the trees being cast on the ground. However, she's rushing into the house to throw a 12:30 luncheon. If it were actually 12:30, the sun would be high in the sky and there would be very little shadows cast on the ground. (00:08:20)
Continuity mistake: In the part when Lina and Doon are looking at The Book of Ember, they open it to a few pages in. But in a later shot, it shows they are near the middle of the book.
Factual error: The Moon is pushed into a "more elliptical" orbit. When the orbit it shown, it is more eccentric than the Moon's real orbit. However, it is centered directly on the Earth. This violates Kepler's first law of motion, which states that a natural satellite has the primary body at one focus of an elliptical orbit. In other words, the Moon should come much closer to the Earth at one end of the ellipse, and recede very far from it at the other end, rather than receding to the same distance in both directions.
Continuity mistake: When Maya gets in the car to go to the White House, she's in a blue outfit, but is in a brown skirt and pink jacket when she gets there. Despite the fact she could've changed in the jet, she wouldn't have known she was going to be on a private jet, and so would've been wearing what she intended to wear. (00:13:00)
Revealing mistake: When the cop makes a mold of Dave's face from the impact site, there are nostrils in the mold, which are not possible to make with such an imprint.
Character mistake: On Taylor's phone it says she dies at 8:32PM, but Beth says 7:32PM, when reading the message. (00:27:05)
Continuity mistake: When Dacyshyn drags Mulder by his legs and brings him to the shed, he goes past the tree stump with an axe embedded in it, but in the close-up of Mulder's torso there is some debris on the tree stump and the axe has disappeared, then the axe reappears still embedded in the wood. (01:31:10)
Continuity mistake: When Nick and Bobby are playing craps in Rusty Nail's barn, Nick rolls "chest," resulting in Rusty branding Bobby with his R key chain. Rusty puts the red hot key chain in Bobby's shirt pocket and holds it against his chest. When Rusty lets go, you can see a hole has been burned into Bobby's shirt. The very next shot, Bobby is rolling the dice and his shirt is intact. Later on at the very end of the film, Bobby's shirt has the hole in the pocket again. (01:13:50 - 01:15:00)
Continuity mistake: During the Deathball Match, the booth window is smashed and Wernstrom gets knocked onto the court, however in the next overview shot, the window is intact and he is still standing behind it. (00:15:10)
Revealing mistake: When Stacy exits the tent before cutting herself with the knife, the rock walls behind her "shake" like they are a set or projection. It's odd.
Continuity mistake: When the mayor of San Francisco signs the new 'gay rights bill,' he puts the pen to paper with his left hand in the far away shot. When the camera cuts to the close up of him signing the bill, he's writing with his right hand.
Plot hole: In the scene where Ba'al goes through the stargate and arrives in 1939, the event horizon from the stargate puts a hole in the haul of the ship. Later when SG1 goes through the stargate the hole is covered with ice. The event horizon created from SG1 would have been the same as the previous one and removed the ice from the hole.
Factual error: When the soldiers return to HQs, the American flag, hung vertically over the entrance, has the blue field with stars on the right. The flag, when hung vertically, is supposed to have the blue field on the left..
Continuity mistake: Near the end, the tank's turret is seen turning. Camera does a quick cut and it's back to where it was before. Camera cuts and it's turning again.
Factual error: All the soldiers that have rolled up sleeves have them rolled up Marine style (with the inside of the sleeve showing) despite being US Army.
Revealing mistake: When Ami's chest is being drilled by the "drill-bra" at the end of the movie, you can see blood flowing from her chest, obviously because of the damage the drills are causing her. Yet, later, you can see absolutely no cuts or marks on her breasts or upper chest, where the drills were penetrating her skin. The skin is simply soaked with blood.
Factual error: There are Velcro straps holding the pads on the blocking sled, and there is an end zone goal post with one base. Both of these items did not exist until the late 60s.
Factual error: The scene that takes place at the Ford release of their 1971 models has two Mustangs driving to the event. The one in front is obviously a 1973.
Factual error: Approximately three quarters of the way in to the film, there is a close up of a German soldier handing an officer a file of documents. The helmet that the soldier is wearing is a post war 1960s version. This can be determined by the lack of an air vent and rivet on the side of the helmet.
Factual error: In the scenes of the world, when they show the plane flying between destinations, the location of Dublin in Ireland should be at least 50 miles further north along the coastline, as Dublin is not on the south coast of Ireland.
