Character mistake: In the scene when they do the weigh in, the camera man recording Ben does not even have the tape door pressed into the camera, so nothing is being recorded.
Character mistake: When the coach is eating a sandwich in the locker room, there is a headline in the paper he's reading that says, "Diamond Backs rattle Timber Wolfs..." Diamondback is one word and the plural of wolf is wolves. (00:45:00)
Character mistake: When in the mineshaft Trevor says that magnesium is used in gunpowder. That is not correct.
Character mistake: When Barb introduces herself to Flint, Steve calls her a monkey, and she corrects him saying that she's an "Orangutang", pronouncing the G at the end. But the correct word is Orangutan, with no G sound. Barb would surely know this, as a genius ape.
Character mistake: Near the end of the movie, Charlotte says she doesn't have the strength to climb down into the crate. Two seconds later, she climbs down to comfort Wilbur, then climbs back up. Even if she couldn't go all the way to the crate, she was low enough that Wilbur could have carried her there himself.
Character mistake: Before he scampers inside to spy on the humans, Claudius tells the other animals, "I'm your mouse on the inside!" Maybe he should check a mirror while he's in there. Claudius isn't a mouse - he's a rat.
Character mistake: When young Alan is talking young Sarah, he says that he found a board game at the factory. Alan didn't find the game at the factory. He found the game across from the factory at a construction site.
Character mistake: When looking at the newspaper about Chester Copperpot, the caption under his picture reads, "Reclusive scavenger claims, 'I have they key.'" It should read "I have the key."
Character mistake: Before the junk man drives away he calls Mr Coggins "Bill." The correct first name is George.
Character mistake: At the ravine, upon learning that the bridge doesn't exist yet, Marty states to Doc "We can't wait a year and a half for this to be built". If you carefully look at the sign, it says the bridge is opening Summer 1886. That's under a year away, not a year and a half from Sept. 1885.
Character mistake: At the beginning of the movie, Marnie states that she is 13 years old. When Grandma Aggie comes to visit, she tells Mom that it is Marnie's 13th Halloween. Since everyone celebrates their first Halloween before they turn one, if Marnie is 13 the events of this movie would occur on her 14th Halloween, meaning her powers would have faded by now.
Character mistake: When Mike pulls out the first Scare Report, the word "yield" is spelled wrong.
Character mistake: When they find a Suicine, they ask Oak and he says it's a Swecon.
Suggested correction: I watched the film, and Professor Oak pronounces Suicune's name correctly.
Character mistake: The Daily Planet newspaper headline "New publisher for your favourite paper" has "favourite" is spelled the British English way. Since Metropolis is in the United States it should be spelled "favorite."
Character mistake: When Raphael is chasing Casey Jones after their fight he vaults over a taxi hood, never takes his eyes off Casey, but he somehow loses him.
Suggested correction: 2 things are happening; a shell backed stocky Raphael is chasing a lighter human athlete Casey. Casey has freedom of movement, whereas Raphael can't stray much from the shadows in hiding. :-) A knocked out Casey wouldn't be helping the Turtles out of the next evening with that memorable entry so I'm glad Raph lost the chase.
Character mistake: When Fred and Barney are about to be hanged, Betty and Wilma are in the car on their way to save them. Betty calls Wilma 'Willa' instead of Wilma. (01:09:00)
Character mistake: Gail reads right through Katie's poor excuse about crotcheting, and says she won't go to the ball "after what you pulled today with Guy." She did not do it (well she didn't do anything, but 'supposedly did') today, but yesterday. (00:31:00)
Character mistake: The score board during the game shows the Gas House Gorillas have the scores 10, 28, 16 and 42, for a total of 96 runs. But later on the announcer gives the score as "Bugs Bunny 96, Gas House Gorillas 95."
Character mistake: When Tom goes into cardiac arrest, the doctor uses the defibrillator paddles on him, but she uses them whilst the hospital gown is still on him. A defibrillator must be used on bare skin if the electricity is supposed to get through to his heart. (01:08:55)
Character mistake: On the side of the boomerang box, there are words reading "Return's to owner." It should read "Returns to owner."
Suggested correction: The construction might very well be part of the factory, a new factory building for example.

The sign at the construction site said it was an "Executive Office Annex" that they were building.
Bishop73
Even though the sign said it was an Annex, construction was still being done outside of the main factory where Alan found the game. Not inside of the main factory itself.
