Character mistake: When Craig gets the milk out of the fridge he takes it to the table and pours it on his cereal. He looks surprised when there isn't much in the carton. He would've known this from the weight of the carton when he first picked it up.

Character mistake: More than once the crew of the submarine salute the Captain while uncovered in the hallways of the sub. Sailors never salute without their cover on.

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)

Character mistake: When Bruce is looking at Chase's various clippings of Batman on her desk while she's tending to the tea kettle, there is a paper that says "Diagnosis Form #39," and just above it, the word "schizophrenic" is incorrectly spelled as either "schizofrenic" or "schizoprenic" (a metal clip is partially covering the last six letters of the word, so it's hard to determine whether it's an "f" or a lone "p" where the "ph" should be). (01:03:11 - 01:03:32)

Character mistake: When the group is escaping from the killer gorillas, they find a cave and Ross say "It's a geode, a giant diamond." A geode is not a diamond at all, it's basically a hollow rock with crystal formations inside.

Character mistake: When Lucky the dog is chasing Slick the cat, into John and Ariel Gustafson's house, Ariel yells out her husband's name, she actually yells out the actor's real name Jack instead of John, the character's name. Pay close attention, it could be easily missed. (01:07:10)

Character mistake: The reporter refers to a "box of ashes" being buried in Westlake's grave, whereas in the first film, all that was buried there was "an ear", which was all they could find of his body.

Character mistake: Lucy asks the hot dog man for the usual: mustard and Coke. She gets the hot dog but no Coke.

Character mistake: When Bond is jumping from the dam in the opening sequence, you see him 'clip in' twice, once attaching the rope to his feet, and once attaching the rope to the dam. He is using screw-gate carabiners, large clips that have a small bevel gate on them that secure them shut. Yet Bond doesn't screw them shut - all it takes is a simple flick of the fingers and they're done. This means that they're not as safe as they should be, and could potentially open - particularly when doing something as stressful as diving off a dam. You would have thought that as Bond's parents 'had the luxury of dying in a climbing accident' as Trevelyan puts it, he would take more care over basic safety procedures when using ropes and climbing equipment.

Character mistake: When the high roller Ikachawa returns to The Tangiers, Rothstein said he's betting $1,000 instead of his usual $30,000, so when he won, it didn't feel like he had won $10,000 (10 $1,000 bets), but felt like he lost $90,000, alluding to the fact that betting 1/30th of his normal bets made him feel even though he was winning $1k a hand he was missing out on the other $29k, or losing that. At ten hands won, at $1k/hand, he really would have felt like he was losing $290,000, not $90,000 as Rothstein says.

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.
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.
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.

Character mistake: Salt states that the range of their Hughes OH-6A helicopter is 400 miles. The actual range of this model is 267 miles. (Source: FAS.ORG).
Suggested correction: The FAS site lists 4 different ranges, but according to Boeing's own website, the range was 413 miles.
Suggested correction: The range of the OA-6 is 380 statute miles.

Character mistake: You can see many of the "terrified" people smiling when running through the arena hallways.

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 Marilyn asks Henry "Do they know they're not on the air?" her finger is pointing just below her face. In the next frame with the camera now facing the pair, her hand is down at her lap. (00:47:00)

Character mistake: During the St. Ives riddle, Simon gives them 30 seconds to solve the riddle and call back. But it takes them 65 seconds to call, to which Simon says they're 10 seconds too late. And, after 42 seconds, McClane says they only have 10 seconds left.

Character mistake: When Billy comes back from high school to visit his 3rd grade class, Ms. Vaughn is teaching prime numbers. The board reads "1, 3, 5, 7, 11" with the words "prime numbers" below it. "1" is not a prime number and it is written on the board, and "2" is a prime number and it is not written on the board.

Character mistake: Circus Liquor is actually located in North Hollywood, not Sun Valley (although Sun Valley is just a few short miles away from there).

Character mistake: Xavier is exiting an elevator and turning down a corridor to meet the other agents before bursting in on Sil and the murdered Alfred. When Sil flees it is revealed she murdered the maid to gain access to Alfred's room. To everyone's surprise the maids' dead body is positioned right outside the elevator. Surely Xavier would have seen the dead maid when he came up?

Character mistake: When Sammy, the postman, arrives on the scene, he rushes up and attempts to take Vera's pulse in her neck. Unfortunately, Sammy's fingers are nowhere near the carotid artery, so he couldn't take her pulse.
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.
When Tommy is made president and introduced, that's at the end of the film. So, no, his dad didn't literally just die. Plenty of time passed. But the correction is wrong on its premise, but that's not to say a different argument couldn't be made why the mistake is wrong.
