Other mistake: George should be dead or at least seriously injured after he falls from the roof of the warehouse.
Suggested correction: George falls onto the two thugs, breaking his fall. Granted, he would still likely be injured, but the distance of the fall is probably no more than 15 feet. Likely not fatal and the fall is broken.
Corrected entry: There's a scene where two of the children are playing a video game. They're both holding controllers and talking as if they're both playing at the same time. But the game they're playing is "StarTropics" for the NES, which is a one-player only game.
Correction: The game is Super Mario, and only the girl is holding an official NES controller the boy is using a makeshift gauntlet controller.
