Plot hole: There's no way that Eddie and Nana left the flooded theater without getting a single drop of water on them. The water flooded up to the ceiling and there's no other way to exit besides the front doors, and Moon's secret exit, which also floods. They do not leave through either way.ryderpoints
Factual error: In the movie, we see the Statue of Liberty with its current bluish-green color. The statue only got that color over time, and as it was still being built, it should be its original brown.
Plot hole: When the dome of crystal collapses, all the animals inside immediately grow old, including Brook, implying that the magic from the crystals is completely gone. However, when a tiny piece of crystal lands in the hot spring, it creates a 'fountain of youth' which the animals then bathe in to regain their youth. If that little piece of crystal worked, then why didn't the many crystals from the broken dome still work? Also, how is Brook able to leave the fountain of youth and go looking for Cid at the end of the movie without growing old?
Revealing mistake: Towards the end of the movie, the principal puts on his hat which turns his hair green. But you can see the green paint has already been applied before he puts his hat on.
Other mistake: The actor, Laurence gets into a fight with two bad guys who mistake him for Norm. Laurence is sitting on top of the two bad guys after the fight and Laurence then punches one of the bad guys so hard that he flies across the street. The problem is, Laurence was sitting on top of the bad guy throughout the whole punch. (00:32:40)Casual Person
Factual error: When Tripp enters the garage and we see his truck in progress, he states that the truck will have 425 horsepower. The Hemi pulled out of the Terravex truck is not a 6.4L Hemi (only a 5.7L Hemi) and even if it was a 6.4, they only produced 410 horsepower in the heavy duty trucks. The 5.7L Hemi makes 375 horsepower in the trucks and 390 horsepower in the cars.
Continuity mistake: In the first scene, the old alien man comes to pick up his spaceship and Ratchet instructs him to "Now, let's fire up that mag booster." The old alien pushes the switch forward to start the mag booster. Later in the movie, Ratchet flips the switch backwards to "engage mag booster" as Clank commands. (00:06:30 - 00:26:30)
