Character mistake: During the movie the cat Winky is referred to as male, but much later in the movie is referred to as female.
Character mistake: Garfield calls two different dogs Boomer. The first is a white dog at the vet. The second is in the scene at the train station when the dogs from the pound come in Garfield calls Spanky, the brown dog, Boomer.
Character mistake: Archimedes says he told Arthur not to pull the sword out of the stone. He didn't, he pointed it out in the churchyard to him instead.
Suggested correction: Archimedes was trying to be helpful when he pointed out the sword so Merlin could take it to the tournament. But after it became a big issue with the rays from heaven and the legend, Archimedes thought he might get in trouble so tried to act innocent by fibbing. It was deliberate and in character, not a character mistake.
Character mistake: When Holly and Amber go to see Amber's uncle at the Bistro, they say the 'report' is due tomorrow. However that day will be Sunday (no school!), as previously it was mentioned that the day was Saturday.
Character mistake: When Bob Munro (Robin Williams) is behind the tractor, the speedometer shows that it is below 10mph. He then states that they are going twelve. How could he if they didn't reach 10mph yet?
Character mistake: When Gwen Piper is talking to Aggie in the soup pot at the beginning of the movie, Aggie addresses Gwen as Linda.
Suggested correction: Aggie says Gwen darling.
Character mistake: Meggie seems to have a different accent from her dad, Mo.
Character mistake: When Jack offers to sell his cow to the butcher, the butcher says "There isn't much meat on him." Jack points out that the cow is a "her", but after the sale, he says to the cow, "Be a good boy."
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 Dracula puts Johnny on a time-out, it is shown that Dracula has the ability of psychokinesis. Yet during the scene when Mavis visits the human village, when one of the dressed up zombies loses its head, Dracula jumps into the scene to physically put the head back to its body, further risking being spotted by Mavis, which he wanted to avoid. (00:16:15)
Suggested correction: Using this power would also be a risk of Mavis finding out because his magic has blue effects around which she would spot.
I doubt that, she was facing the opposite direction of the headless zombie the entire time, and the zombie didn't stand too close to her. However, I have realised that the magic does seem to make sound, and the headless zombie did stand close enough to Mavis for her to would have heard Dracula's magic if he were to have used it.
Even with the sound, I doubt she would have noticed when there are what looks like villagers approaching her with pitchforks and torches.
Character mistake: When Sam pushes Freddie off the plane, his mother puts on the parachute and jumps out as well. She is in such a hurry, that she doesn't buckle the straps across the front. In real life, as soon as the parachute is deployed, the resistance would cause the parachute to come off and she would likely fall to her death.
Character mistake: The sign outside the Fortune Teller's tent says "Madame Zaza", but when Droopy enters the tent, Spike introduces himself as "Madame Zazu."
Character mistake: When a flattened Yosemite Sam returns the flattened ball to his wife, there is a theatre across the street that uses the English spelling of "theatre" instead of the American "theater."
Character mistake: When we see the sign in the window of the music shop, it reads "This Week Dance Record" which doesn't make much sense. Surely it was meant to read "This Week's Dance Record."
Character mistake: On the side of the boomerang box, there are words reading "Return's to owner." It should read "Returns to owner."
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: On the sign outside Dr I.Q. Hi's headquarters, the word "Stratosphere" is spelled "Stratopere."
Character mistake: When Tom opens the "Life with Tom" book to Page VII, we see the page and there is a typing error in the very first line. The word wasn't is misspelled as "was'nt."
Character mistake: When Bugs is reading the book, he says "Octopuses", but when we see a close-up of the book, it reads "Octopus."
Character mistake: At the beginning of the cartoon, there is a sign which reads "IF YOURE LOOKING FOR FUN" with no apostrophe.
