Character mistake: When Wood is telling Harry the rules of Quidditch he says that if you catch the Snitch the game is over, which is true. But then he also says that which ever seeker catches the snitch, their team wins, but that isn't true. Granted that the 150 extra points probably would give you the winning lead, but as JKR pointed out in the 4th book at the Quidditch World Cup, you can catch the Snitch but lose the match. And you'd think explaining the rules to a first-timer you would want to get it right. (01:05:40)
Suggested correction: The team whose "seeker" catches the "snitch" would win in over 90% of matches. At this point, in the film and the book, while Harry Potter has discovered that Quidditch is popular in the wizarding world, he knows nothing about the rules or how to play. Oliver Wood is giving Harry Potter his very first introduction to Quidditch. So maybe it is acceptable for Oliver Wood to give a general overview of how Quidditch works, rather than outline every nuance and detail of every game ever played.
Character mistake: After Spike comes out of the evolution device, he asks Iggy "Do you know what the square root of 26481 is?" And then answers "191". 191 squared is actually 36481. (00:47:20)
Character mistake: In the courtyard of the castle there is an anti-aircraft gun. You could probably not find a worse place for a gun like that even if you tried (except maybe if you put it inside, in a windowless room). In the position it is placed it can only fire at targets directly above the castle. What you want to do is fire at targets before they reach the castle. It would be better if they placed it on the roof, or even near the village below.
Character mistake: When Tris and Christina are going to rescue Four, Tris asks how to use the drones. When Christina tells her that she must use her left hand she can be seen using her right hand to control them.
Character mistake: In a scene when Watney is recording his video log, he imagines what would happen if his pressurized shelter suddenly would break. He concludes that he would implode, but the correct wording would be explode.
Character mistake: When they arrive at the motel, the mother says that the grandpa is in room 13, but when he opens his door it is room 208.
Character mistake: The word "Storyboard" in "Storyboard Artists" during the end titles is misspelled "Stroryboard". (02:05:00)
Character mistake: The police are marching Matrix out of the gun shop, they didn't even put hand-cuffs on him! I think I would put hand-cuffs on a guy who just smashed open a gun shop and was stealing all the guns he could get into his hands. (00:55:50)
Character mistake: In the scene where Rick Marshall is playing the Banjo, he says he has been "doing some thinking with just him and the old four string". His banjo has five strings and you can see the five strings when he lays the banjo down.
Character mistake: When Tommy is being shown his new office the glass reads "Thomas R. Callahan III, " but when Tommy is introduced as the new President of the company he is introduced as "Tom Callahan, Jr." which would be his dad. (00:11:35 - 02:11:55)
Suggested correction: It is possible (probably not common) to be a "III" and a "Jr." If you are named after your father, and he is still alive you are a Junior. If you both share the name with another member up the family tree say your great grandfather, then your father would be a "II" and you would be a "III." But since your father is still alive, you can still go by junior. I've known one person in this situation.
I guess you missed the part of the movie where his father died. He's made the new president because his dad is dead, not alive, negating your main point.
His dad literally just died, and most people don't know the specifics of the naming rules. That would be a character mistake of the person introducing him.
Character mistake: When Maximus is talking to Marcus Aerelius, he mentions that his wife has black hair. But in the scenes where we see her, she actually has brown hair. (00:24:40)
Character mistake: When Stan inflates himself, Michael asks, "How'd he do that?", implying that he doesn't know the rules of the Looney Tunes world. Since Michael was rolled into a ball by the aliens earlier in the film, this shouldn't be too much of a surprise.
Suggested correction: When Michael was rolled into a ball, he wasn't concerned with how that was possible and soon after he forgot about it. He was more concerned with dealing with the Monstars at the time and, in particular, helping his cartoon friends preparing for the game. When Michael witnessed Stan being flattened and inflated, it looked particularly strange and unfamiliar to him, unlike before as he couldn't watch himself experiencing being rolled into a ball. And that is what triggered his response about questioning how it was possible.
Character mistake: Those are the most haphazardly secured cases of nitro I've ever seen in a movie. Couldn't they spare a shoelace or duct tape to secure the top?
Character mistake: When Jimmy explains to the kids of the town where the aliens took their parents, he mentions the origin of the aliens being somewhere in the Orion Star System, 3 million light years away. The Orion system is way closer than that. It is actually less than 1400 light years away from Earth. 3 million light years away would place them further than the Andromeda Galaxy.
Suggested correction: This shouldn't be a character mistake. A genius like Jimmy would know something like this. It's basic astronomy.
That's exactly why it's a character mistake. A character mistake is when a character does or says something that they shouldn't based on who/what they are suppose to be, or something a character wrongly states as fact when they should know better.
Character mistake: Some characters use the letter "s" at the end of a Pokémon's name when the plural of a Pokémon is just its name. The best example is when Pikachu says, "Roger must've sent the Greninjas to cause the car crash." Being a Pokémon himself, there's no way Pikachu, out of all characters, would say that.
Character mistake: There is no way an operative of Q's position and experience would have plugged a device taken from a bad guy into their network. Especially as they had had a security hack only a few days earlier, and this was a security establishment. It would have been thoroughly tested and checked on a stand-alone, air-gapped setup first.
Character mistake: All the characters wearing gas masks are wearing them with the straps over the hoods. I was army trained, and you always wear the mask next to the skin for best seal, with the hood over the top.
Character mistake: The actor who played FBI agent Ross is Lennie James, who is an English actor. When they are searching for the girl in the parking garage of her building, he orders the SWAT team and other agents to search everywhere, under the cars and to "check the boots." He says this twice. Boot is the British term for trunk. He should be telling them to check the trunks of the cars, not the boots.
Character mistake: In a conference with Crockett and Bowie, Travis states that Fannin in Goliad is preparing to relieve the Alamo and will be ready to "march south by the end of the week." Goliad is 90 miles south of San Antonio. To relieve the Alamo, Fannin would need to march north.
Character mistake: Early in the story Dr. Gibbs rationalises the story to come by using two cars traveling the road at greatly different speeds to illustrate "Einstein's theory of relativity". He basically says that the slower moving car seems to stand still as seen from the much faster car's point of view. But in real Einsteinian relativity, just the opposite happens. When two reference frames are traveling with respect to each other, each sees the other's time advancing more quickly.
