In the scene where Ness and Nitty are on top of the roof of the court house. Ness grabs Nitty and runs with him toward the edge of the building. The distance between Nitty and the roof access door changes. It looks like Nitty is only a few feet from the door when he is talking to Ness, but when Ness grabs him and starts running with him to throw Nitty off of the roof, Nitty and Ness are about 15 feet or more away. Did Ness grab Nitty, drag him backwards then run with him forwards? I think not.
