Character mistake: Early in the film in the scene in which Precious is in math class just before being called to talk to the principal, on the blackboard someone, presumably the teacher, has written REQUIRMENT, which is a misspelling of "requirement"
Character mistake: In the exchange at the train station in district 2, Katniss says how she killed Cato in the 74th games, and Cato killed Thresh and Thresh killed Clove etc However Cato didn't kill Thresh - he was attacked by the mutts and killed by them. (00:14:50)
Character mistake: At the truck stop, Mark (young Damian) meets with Martin. Martin tells Mark that he had the shedding pills reverse engineered and hands him a piece of paper. The percentages of the 5 ingredients only add up to 90% rather than 100%. (01:29:25)
Character mistake: After Cal goes to the secret lab in Georgia, he and two others go into his new lab. When they enter a cat jumps up on the counter. Dr. Adams says "This is Neutron. We named him that because he's so positive." Neutrons are neutral and electrons are negative. It's protons that are positive. They should have named the cat Proton.
Character mistake: When we first see Sophie her body was slumped over (the spell to make her old) but later on in the movie, her back magically seems fine. (00:00:01 - 01:50:00)
Character mistake: When George throws one of the soldiers through the cockpit door of the plane, you get a brief glimpse at the pilot and co-pilot, both of which are wearing a Bose headphone/mic set. However the co-pilot has his one backwards, with the mic bent from the right side when it's meant to be on the left. (00:44:50)
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: Sam says that Archibald Witwicky explored the Arctic Circle in 1897. But when Frenzy finds the article, it is dated 1895.
Character mistake: In his opening prologue, Burt says the Graboids have been contained to the Northern Hemisphere, showing a map highlighting the Graboid attacks of the first film in Nevada and the second film in Mexico. However, it overlooks the Graboid/Shrieker attack in Argentina, in the Southern hemisphere, shown at the beginning of Tremors 3, an incursion Burt personally put down. It's not like it was classified - characters in that movie talk about it being reported by CNN, and characters in the Tremors TV series talk about it as well. And it's not like Tremors 3 is no longer canon, since Burt makes two references to being swallowed by the Graboid in that movie (which also becomes a plot point in Tremors 6).
Character mistake: David Dastmalchian is the Polka-Dot Man, hyphenated in the comics, and in the end credits of the movie. Then again, when Waller threatens to kill everyone off, the name of the character appears in print as Polka Dot Man, no hyphen. (01:49:40)
Character mistake: There are signs out front as the Spenglers arrive at the dirt farm. One of the signs is a call back to a scene in Ghostbusters 1984. In the scene, Ray quotes the book of Revelation: "And I looked, and he opened the sixth seal, and lo, there was a great earthquake. And the sun turned black as sack cloth, and the moon turned blood." When Finn Wolfhard reads it he misquotes the line saying "The sun became as black as cloth."
Character mistake: Early in the film we are repeatedly shown the alien character flirting happily with various men, relaxed, confident, even socially forward, in fact often more articulate and socially at ease than the various Glaswegians she encounters. Yet later on, inexplicably, all this social nous mysteriously disappears and she is completely baffled and blindsided by the simplest of social interactions, almost a mute. Since the film has virtually no plot it's hard to see why this jarring turnaround should be so.
Character mistake: When Herr Falkstein introduces himself to Frederick he tells him he has come 5,000 miles to bring him his great-grandfather's will. The ancestor in question was supposed to be his grandfather, not great-grandfather. (00:11:53)
Suggested correction: Victor is Fredrick's grandfather, but not the one who died. Baron Beaufort von Frankenstein died, leaving the estate to Fredrick. Beaufort is his great grandfather.
Character mistake: In the scene where the gorilla type creature has taken out one of the security cameras, they say "one of the creatures just destroyed video four" but if you look, camera four is intact and it is camera two that has been taken out. (01:08:05)
Suggested correction: Monitor names and video names are not the same so monitor 2 which is out, could in fact be displaying images from video 4. On a multi monitor system, there could be tons of video feeds that could be played through those monitors.
Character mistake: Namibia was said to be in West Africa. Namibia is in Southern Africa.
Character mistake: While one of the Soviet mission controllers does speak with a native-sounding level of Russian, the other controllers and the cosmonauts sound obnoxious at times; strange anglicisms or outright English words are sprinkled into the script, such as the word "pressure" in the middle of an otherwise Russian sentence, not to mention the many grammatical errors.
Character mistake: Kathy Ireland as Wanda speaks mostly in a slightly squeaky voice. But in one scene she uses her own regular voice.
Character mistake: When everyone starts counting down to blow up the Violet Dwarf, everyone starts at 10 downwards. Yet 40 seconds later, they are still counting down. (01:19:40)
Suggested correction: Its very common for movies and TV shows to do this. Just because they say 10 seconds doesn't they can't spend more time going through the thoughts in Fry's head.
Character mistake: Jill states that a 5 kiloton nuclear weapon will sanitise the city, however, such a yield is far too small to destroy the city. (00:42:00)
Character mistake: Towards the end of the movie when the Giganotosaurus is attacking the group and Claire gets the rope wrapped around her leg and pulled towards the dinosaur Owen actually shouts Bryce before saving her instead of Claire.
