David Rice: Who are these people?
Griffin: Paladins. Paladins kill jumpers. I kill paladins. Class dismissed.
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.
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.
