Plot hole: The main criminal puts on the "butt inspection gloves" whilst searching the first house, but when Alex sees him through the telescope he pulls down the blinds and has black gloves on. Returning outside, they revert back. However, how does Alex know the criminal donned the rubber gloves (when he describes him to his mother), if he saw what we saw through the telescope - the black gloves?
Plot hole: How would Arnold know about the cop hitting the bus when he was running away from him during the parade? He was far past him at that point.
Plot hole: When the aliens kidnap the adults, the kids are left behind. But all the kids seen are around 11 and younger. Where are the teenagers or young adults? None of them are during the celebration scene nor in the arena on the alien planet.
Plot hole: We don't see any herbivores in the underground world - just fish and little birds. A T-Rex would need lots of big game to survive.
Plot hole: There is no possible way for the chubby mayor to be able to get in Flint's lab. There is no side entry, and the space other characters use to get in is too tight for him.
Plot hole: It takes less than 3 minutes to fill the house with water using a mere garden hose? I mean come on...
Plot hole: About two thirds of the way into the film, Gina comes running into Montebello's to talk to Joe, while Joe bursts into Prestolani's to confront Gina. Of course, in typical romantic comedy fashion, they just miss each other. However, the two pizzerias are directly next to each other, and both characters were using the front doors. Therefore, there is no way that they could possibly have missed each other.
Plot hole: When Tinkerbell tries to find Gruff in winter, she's seen flying with her wings out of her coat; in a later scene, Fawn flies too. After Tink finds Gruff, her wings disappear from underneath her coat. This is a plothole because of how the whole storyline of Secret of the Wings was that warm fairies can't fly in winter weather or their wings will tear.
Suggested correction: Yeah but at the end of Secret of the Wings, they find a way to let any fairy fly in winter.
Plot hole: There is supposed to be no power when the Dragonfly ship reaches the island, but the lights are still on. At first, I thought it was just a lighting trick, but you can see the lights are on in the tunnels.
Plot hole: When Tarzan comes to the hotel to visit Jane, he overhears the bad guys threatening the hotel clerk into giving them Jane's room number. Tarzan then has time to go into the streets and study the hotel for a little while (coincidentally just when Jane happens to appear in her window), climb to the second story and through her window, have a romantic reunion with Jane and explain what is going on before the villains have managed to ascend the one stair from the lobby.
Plot hole: Although Marty rips the fuel line, not all the fuel would have drained out of the tank. Only the fuel that was already in the fuel line would have leaked out, meaning it could simply be patched, bled and the engine would run without a problem.
Suggested correction: A cut fuel line could absolutely drain the tank. Even if not a direct route with respect to gravity, it could still create a siphon effect and drain the tank.
Plot hole: When Pistachio and Jennifer go to the toy convention to find Bowman she says her name is Barbara, and Bowman invites her to his house. When Pistachio comes looking for her at the door (as the German Guy and the Snobby English Guy) he says he needs to talk to Jennifer Baker. Wouldn't he ask to see Barbara instead of Jennifer? Also Bowman knows her as Barbara and didn't say anything about him calling her Jennifer.
Plot hole: If Happy Chapman is supposed to be allergic to cats how come he doesn't sneeze whenever he is around Garfield?
Plot hole: Gerry's wife uses a rocket boot to break through a window and then slides down a curved wall to get to their son. She does so gracefully and takes off running. Gerry slides and takes a hard tumble and rolls down, landing on the ground. The next shot shows Gerry running behind his wife and not too far away as they reach their son. Even if it was to show a little time passing, there was not enough distance between where they broke the window and their son for Gerry to have picked himself up and catch up to his wife before reaching their son, especially with his wife being a worried mom doing a full on sprint to her kid.
