Other mistake: The film is about a gang of Confederate soldiers after the Civil War, so a black man in the gang would seem a bit out of place.
Other mistake: In the scene where Madonna is pouring candle wax on Defoe, once they start having sex (with Madonna on top), you can clearly see Defoe's manhood poking out where it shouldn't. I realise they're not actually having sex, but shouldn't it be taped up out of sight?
Continuity mistake: When Curly Bill is shooting up the town while drunk, he fires about 10 more rounds than his six shooter can hold without reloading, and still has a round remaining when he shoots Marshal Fred White. In the 1880 court hearing held after Marshal White's death, Curly Bill still had 5 rounds remaining in his pistol.
Visible crew/equipment: In the fight scene on the stairs near the end of the movie, the camera shot looks up and there is a security camera mounted up in the corner. (01:29:40)
Plot hole: At the end of the film Woody shows what a nice chap he is by spending the 'tainted' million dollars at a charity auction. He's just made his problems much worse - he paid his solicitor a large fee to arrange the deal, so he hasn't got a million in the bank. That cheque is going to bounce so fast it will crack the plaster on the roof of the bank, and bouncing a million dollar cheque is a serious criminal offence in the US. (There is no way enough interest could have built up to cover the difference, either).
Visible crew/equipment: Between the beginning of the movie and the end of it inside of Jesse's shop when the camera is facing the entrance and Jesse's desk look real closely at the window reflection in the playroom with the children and you will a see a man wearing a white shirt holding a camera prompt against her desk.Kevin Brown
Revealing mistake: The oil lamp carried by Mary when she first finds Colin has a flame that never flickers, and is likely an electric lamp.
Continuity mistake: When the bobsled team is getting their act together in Calgary, there's a scene of them pushing off with an unpainted bobsled. In the shots of the feet of the guys pushing at the back of the sled, you can see that the lower back of the sled is painted black with green stripes, the colours that they paint the sled in a scene a few minutes later.
Visible crew/equipment: During the scene where the whole family is first driving into Beverly Hills, in the scene where they give the finger to say hello, the camera crew can be seen in the reflection of some of the cars.
Continuity mistake: At the beginning, when the president lands in the helicopter, the shots go back and forth between the rotors spinning, and the rotors stopped. (00:02:10)
Continuity mistake: When the two Ninja robots fight, the robot on the left loses his head before the blade strikes.
Revealing mistake: When the boys' rival team challenges them, all the boys throw their gloves down, except Yeah-Yeah. When they all go to pick them back up, Yeah-Yeah has to pretend to pick it up.
