Continuity mistake: When Jim pushes John out the car, in the shot where John is lying on the road, his head is on the road's white stripe, yet when it cuts to a closer view, his chest is on the white line, not his head. (00:12:30)
Other mistake: When they first get into space and Tish removes her helmet her left earring is free floating, which would be expected in zero gravity. But after this first shot, her earrings hang down as effected by gravity. Also all three of the girls hair hang down with gravity the whole time they are in space. (00:54:45 - 01:03:15)
Deliberate mistake: During the gunfire of the Portuguese soldiers at the end, seconds before Jeremy Irons is killed, an old Indian woman is shot in her chest, but the actress/extra forgets to react and continues walking.
Other mistake: How does Dola know that Sheeta's pigtails were shot off? They had been outside in their aircraft the whole time and once Dola got Sheeta in a tight hug, the situation doesn't call for any time for her to explain what happened.
Continuity mistake: Watch Gwenda's headrest after she leaves the station in her car. It disappears between shots.
Revealing mistake: A sign's wooden support gets shot at the beginning, but you can see where the pre-prepared weak point is in the support before it gets "shot."
Continuity mistake: At the end of the movie, Spence is seen with Claudia in a western movie. He walks through the swinging bar doors with a cigar in his mouth. He takes a few steps forward and the size of the cigar has nearly doubled.
Continuity mistake: During their escape the three protagonists have to wade through a canal. A few moments later their clothes are dry again. (01:02:15)
Continuity mistake: When Jim and Brandon are knocked into the water, Brandon dies, but somehow manages to grab hold of Jim and pull himself up.
Continuity mistake: Woody Harrelson is just demoted from starting quarterback. He mentions to Goldie Hawn that he makes a great slot back. The next scene is of a slot back making a great run, only the slot back is black. He gets tackled and when he gets up you see a very white Woody with the ball.
Visible crew/equipment: When Isabelle runs from the zombies at the end, cameramen shadows are frequently cast on the zombies.
Continuity mistake: When Roger babysits Robert, the neighbour's son, he begins to cry, so Roger sits with him and watches TV. All of a sudden the tears on the childs face miraculously dry up between cuts.
Revealing mistake: When Lazarus and Klepper's vehicle goes through the wooden crates and flips over, you can see the wooden ramp used to launch the car.
Factual error: The film strongly implies that John Dudley, the Duke of Northumberland, keeps his head (literally) by converting to Catholicism. In fact, he was executed well before Lady Jane Grey was.
Visible crew/equipment: When the Overlord is busy destroying the Diner, when he starts destroying stuff on the counter, you can see the small rods pop up that flip the saucers and glasses into the air. You can also see the compressed air they used, to aid with the effect.
Visible crew/equipment: When Kazihiro turns off the T.V. while the Twisted Sister music video is on, you can see a crew member reflection in the television.
Factual error: In the scene outside the pub, a Ford Sierra is seen driving past. These were not introduced into the UK until Autumn 1982. The film is supposed to be set in 1981.
Continuity mistake: In the scene where Steph is in her second show, there are at least 2 different horses. The manes and tails go from being braided to being unbraided. Also, the breeches change from grey to beige. One of the horses before her round, a chestnut, has one sock, then none, then three, etc. There were multiple (I counted at least 7) horses that played the part of Lightning, who was supposed to be registered with the Jockey Club, which is the Thoroughbred registry. Most of the horses that played him were not even close to being Thoroughbreds.
Factual error: Throughout the film, they play one of Strauss' Four Last Songs, which is credited as being "September." The song actually played is "Beim Schlafengehn."
Continuity mistake: About half way through the video when Casey Meadows and Battle Whitherspoon are finished making love in the mountain cabin Casey is laying on Battle's left side. The next morning when they wake up Casey is on Battle's right side.
