Audio problem: When Matilda is in her car with Derek and on her cellphone with the anonymous hand model he hangs up on her and you hear a dial tone, yet on a cell phone, there is no dial tone. (00:46:35)
Continuity mistake: When Derek and Matilda are driving after leaving the walk off, the vehicle driving behind them is the same vehicle as when they leave the cemetery to go to Hansel's loft. (00:47:45 - 00:54:40)
Continuity mistake: While Hansel is standing in the doorway listening to Matilda explain why they need a place to hide, Hansel's left hand changes a few times through out the scene, C shape & flat on door. (00:54:45)
Continuity mistake: When Derrick and Matilda arrive at Hansel's, watch Hansel's turquoise necklace. It goes inside and outside his shirt a couple of times, while talking at the door. (00:54:55)
Continuity mistake: When Zoolander, Hansel and Matilda are drinking the tea near the end of the movie, the "steam" in Zoolander's cup keeps on changing to from overflowing the cup, to half way down and none. This is without ever refilling his cup. He can even be seen blowing some of the steam out and next thing it's full again. (00:58:00)
Continuity mistake: In the scene where Hansel, Matilda and Derek are in the kitchen, the morning after the orgy, everyone else is asleep in the background. Derek's mobile phone rings and then there is a shot of Matilda. Behind her you can see that they are now sat holding phones up to their ears, then when we next see them they are asleep again. This is because the joke where they all answer their phones was cut, leaving only Derek and the chef who answer theirs in the final cut. (01:01:55)
Factual error: They show the clock on the wall at 6:17pm, but when Matilda is talking to Archie in the office, the L.A. clock says 5:17pm. If they are in New York it would be 8:17pm. (01:06:45 - 01:07:30)
Continuity mistake: When Derek is giving his mobile phone to Hansel it cuts to a close up of Hansel holding the phone before Derek actually gives it to him. (01:09:45)
Factual error: There is one scene towards the end when Matilda is talking to her assistant and two clocks showing the times of Tokyo and Hong Kong are visible on the wall behind. In reality Tokyo is one hour ahead of Hong Kong, but the clock clearly shows Hong Kong as one hour ahead of Tokyo. The Frankfurt clock is also an hour slow, assuming the Chicago clock is the correct one. (01:11:05)
Continuity mistake: At the Derelicte show, Derek is getting his makeup put on. He has black eyeshadow all around his eyes and it kind of "stretches" down his face. When he comes out onto the runway, his eye makeup is different. (01:11:30 - 01:13:30)
Continuity mistake: When Hansel is rappelling down to the D.J. booth, he has gloves on. When he stands up, the gloves are gone. (01:14:35)
Revealing mistake: In the scene where they confirm it's a walk-off between Hansel and Derek, Billy Zane is shown next to Derek saying stuff to stop him and Derek says: "put a cork in it Zane." Billy mouths those exact words and then tries to hide it.
Factual error: The film's plot revolves around killing the prime minister of Malaysia because he wants to ban child labour. Malaysia already has laws against child labour, and has since its time as a British colony.
Continuity mistake: Before the explosion at the gas station, the sun changes between shots.
Answer: It was raining and it was that water from before just running down the semi-sloped road.
