Visible crew/equipment: After they enter the Colosseum in Rome, you get a wide shot of the Colosseum. On the left you see two guys: one is standing behind what appears to be a camera, and the other one is crouching.
Continuity mistake: In the scene where David jumps to a glacier and is hit head-on with a pick-up by Griffin, they then jump into the middle of a guerilla war. The pick-up crashes and a driver is seen at the wheel beside Griffin. The shot changes to wider and when Griffin is seen exiting the car, the driver has disappeared. (01:12:30)
David Rice: Who are these people?
Griffin: Paladins. Paladins kill jumpers. I kill paladins. Class dismissed.
Trivia: When David jumps to the Empire State Building, a woman says, "Maybe, if we're lucky, we'll see King Kong". Jamie Bell, who plays Griffin, was in King Kong.
Question: Why did some summaries for this movie (in newspapers, on websites, etc.) say that David goes looking for the man who killed his mother? In the movie, he seemed to believe that his mother left him and his father, and (if I remember correctly from the theater) didn't suspect that she was killed.
Answer: In the novel that this movie was based on, his mother was killed and David does go looking for the man who did it. Those doing the summaries are just confusing the two different versions.
