Continuity mistake: Wendy has to get on her tiptoes to reach the counter at the hotel lobby. However, when she looks at Carmen99 talking to Van, she reaches the counter comfortably without having to do so. (00:03:25)
Continuity mistake: In the moustached mayor's office, Van opens a drawer and finds "The wonderful YoRoI nation project." The report in close-up rests on a stack of papers that weren't there before the cut - or at least the report was in a different position and you couldn't see papers underneath it. (00:13:50)
Other mistake: The mayor and his crew have moustaches that defy any logic, still it should be noted that Van cuts them when they are extended for several feet but you see the cut and subsequent regrowth starting back from there a normal (for the average human) length.
