Corrected entry: During the blackout when Kyle McLachlan runs down the street after stealing antibiotics from a drugstore, all the lights in the stores he passes are obviously on.
Corrected entry: The gun that Long John Silver uses only fires one bullet at a time and takes at least a minute to reload. In the scene where the boar tribe try and stop him from attacking Kermit and Miss Piggy, he fires the gun at the chief of the tribe. However, he proceeds to cock the gun a second time and point it at Kermit and Miss Piggy without reloading.
Correction: Long John Silver has a second gun in his belt (as shown when they discover the treasure is gone and he is holding off the crew) there is plenty of time for him to drop the discharged gun and pull out the second.
Corrected entry: In the final game vs the Hornets, the visitor team is wearing black shoes except for Larry Johnson. According to NBA rules the whole team must wear the same color shoes.
Correction: The only recourse is a fine. This is how Air Jordans became so popular. Michael Jordan breached the rules wearing them during games and Nike paid the fines. It's certainly possible a player as popular as Larry Johnson has a similar deal in this movie.
Correction: A lot of stores have generators for just such instances. Especially in an area that would have to worry about earthquakes causing power outages. (During the Northeast Blackout in August 2003 there were plenty of stores that had generators and therefore had lights on.)
