Character mistake: When Bower is banging on Payton's hyper sleep chamber from the outside it says Payton, but when it cuts to looking from inside out, it says Bower.

Character mistake: When looking at the various items in his safe deposit box, one of the passports has the name Henry Reed. However the serial at the bottom of the passport is mistyped as REED/HENTY. (00:41:25)

Character mistake: At the trial, the witness said that "With the first shot, we lost our gravitational field. I found myself weightless, and unable to function." However, the first shot caused the ship to start listing to port. It was the second shot that caused the gravitational failure.
Suggested correction: People misremember events all the time, especially if the events are unexpected and chaotic. At best a character mistake.
I called it a character mistake.
He could also simply be lying in order to explain why he did not do whatever he should have after the 1st shot, since he was an easy target for the intruders and did not die in battle, which would have been honorable. Klingons are not the most honest of people.

Character mistake: In Pitch Black they established the system they crashed in (M-344/G) had 3 stars. Jack stated it when the 2nd sunrise started, and the solar system model also had 3 stars. In this film when Boss Johns starts asking about M-344/G he says it is "a backwater system with 2 suns and 1 habitable planet."

Character mistake: While pitching his shrinking machine to NASA Szalinski claims that reducing the size of a rocket's payload would result in "staggering" savings in the fuel required at takeoff. However, he makes it clear that his machine works by reducing the space between atoms, meaning that the shrunken object weighs the same as the original. Weight is the critical factor in calculating fuel consumption, not size. Anyone at NASA would pick up on that instantly.

Character mistake: Shortly before the drone chase scene Cooper tells Murph to put the truck in second gear. She pushes the gear lever forward, however on the 6-speed manual in the Ram 3500 second gear is in the back row.

Character mistake: In the movie they grab Genghis Khan in 1209 which would have been correct, he ruled Mongolia from 1206 to 1227. In the presentation at the end they say in 1269 he did this and that, that would have been Kublai Khan's reighn of terror in Mongolia.
Suggested correction: Bill and Ted have proven not to be that smart. Easy for them to get those things confused.

Character mistake: After killing three of the 'new' soldiers, Todd says that there are seventeen left. He then kills about another thirty.

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: In her first walk through the city with Dr. Ido, after feeding the dog her sandwich, Alita takes a flyer and reads it. Between the lines that read "Wanted" and "Murder" there is a line in Spanish that says "Querido para el asesinato." It should say "Querido por el asesinato".

Character mistake: The movie starts with shots of the moon Io and the company's operations, with typed descriptions at the bottom of the screen. Guess they couldn't afford a proofreader. They spell dependents as dependants, marshal as marshall, and principal as principle.

Character mistake: During the first big battle between the Martians & the U.S. Army, the Martians use their heat ray to vaporise people and equipment. Dr. Forrester, a physicist, then quickly speculates, "It neutralises mesons somehow. They're the atomic glue holding matter together. Cut across their magnetic lines of force and any object will simply cease to exist." During the '50s mesons were theorised to hold atomic nuclei together strongly. But if the Martian rays worked as the Dr. guessed, then objects wouldn't just vaporise. They'd explode with the ferocity of nuclear weapons.

Character mistake: When James enters and exits the laboratory, the door has a sign on it that warns for radioactive materials. The laboratory actually contains a biological weapon. Therefore the door should be marked with a bio-hazard symbol. (00:41:00 - 00:42:00)

Character mistake: When Ripley asked the doctor how they "got" her, he replies from blood samples on Fury 16. This is in reference to the planet in Alien 3, but it was called Fury 161. (00:11:00)

Character mistake: In the Air Force One scene, when lightning destroys one of the plane's engines, one of the pilots tells a co-pilot to inform Metropolis Airport that the president is on board the plane. The crew is unnecessarily repeating themselves: just a few moments before, they radioed in that "Air Force One" was on approach; the plane would only have that call sign if the president was on board.

Character mistake: At the beginning of the movie Marty is turning on a huge guitar amplifier. The two switches for the filaments are misspelled. They are shown as "filiment." (00:03:25)

Character mistake: When the police scan Leeloo the first time, the computer reads "Commencin" instead of "Commencing."

Character mistake: When Troy is getting the bomb ready, the screen shows it will blow in 216 hours, which is 9 days. Yet the agent tells Archer it will blow in 6 days.

Character mistake: Hellboy's stone hand is on the wrong side when he's fighting the first giant. (00:32:50)

Character mistake: When Mary is in the execution chamber, about to be incinerated, there is a voice over of the countdown till her death. They count back from 9 seconds and say 8 seconds, 7 seconds, 6 seconds, etc. The count is too slow. Every time they say a second, it's actually two seconds having passed. (01:22:10)
