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.
Continuity mistake: When David Bowie steps forward to Hansel and Derek, he grabs his hands around their shoulders. As the shot changes from Bowie's face to Hansel's, his hand is gone from Hansel's shoulder, but after the shot turns to Derek and then back to the view of the three of them as it was from the beginning, his hand is back. There's a shot of the back of Hansel's neck with no hand, the angle changes to the front again and the hand is back.
