Factual error: The radar guided SAMs are consistently evaded/triggered by the pilots' flares, which in reality only work against heat seeking missiles. Radar guided missiles would be defended against using chaff, basically clouds of aluminium foil strips. It was mentioned in some interviews they didn't want use chaff as it wouldn't really be visible for the audience - hence why they only deploy flares.
Continuity mistake: The mole by Christian Bale's eye switches sides when he's in the oasis near the start, presumably a flipped shot.
Factual error: The story is set in 1976. "Funkytown" is used in the movie and the end titles. The song was not released until 1980.
Deliberate mistake: The baddies somehow manage to place the net under the two humongous ships by simply digging with their shovels in a matter of minutes, when they would need a bulldozer and several hours instead.
Visible crew/equipment: During the beginning of the film whilst Tara is walking through the house, in the window to the right of the front door the camera guy can be seen during both scenes that take place during the hallway shots.
Continuity mistake: After Becky charges the drone she climbs down without refitting the glass cover. Later a buzzard lands on the top of the tower, on the red cover.
Factual error: The deer in the forest somehow does not hear the giant dinosaur approaching, so doesn't run away. (01:21:10)
Suggested correction: A different interpretation is that the deer knows the difference in the sounds - gurgling/roars of an approaching herbivore versus carnivore - so it didn't perceive it as a threat until it got unusually close (so the deer looked to see why). The dinosaur flung the deer aside, then proceeded to eat the vegetation where the deer was. It isn't likely that the dinosaur (if a carnivore) would toss aside a fresh deer meat brunch in favor of some green brush.
The therizinosaurs were herbivores.
Factual error: The satellite phones don't work as they should. They're somehow still able to use them to communicate after the moon has got close enough to the earth to cause enough damage to the satellite network that it'd no longer function, and can also make and receive calls while under tons of rock.
Factual error: El Paso, Texas, where the entire movie is set, is nowhere near the ocean or large enough bodies of water where a marina with moorings for megayachts could be located. The yacht scene, while fanciful, could not have taken place in El Paso or anywhere reasonably nearby (even by US standards).
Other mistake: Among the credits for the film's music are "principle first violin" and "principle second violin." The correct word is "principal."
Other mistake: When Tsireya is shown swimming with Aonung and Rotxo, her right shoulder strap is glitching through her shoulder. It then proceeds to slip back out of her shoulder and into its correct place. (00:59:10)
Other mistake: When Batman is video calling the Riddler and passes the phone over to the D/A, you can see Batman's face still looking at the phone in the reflection of the Riddler's glasses.
Factual error: The opening states the location as Bristol, England. Santa is drinking in a pub on Shirely Street (neither the pub or the street exist in Bristol), then shortly after is shown leaving from the rooftop, on his sleigh, with multiple high rise buildings in the background. Bristol does not have high rise buildings in the main city centre, only a few blocks of flats, which all have flat roof tops, not like those depicted.
Continuity mistake: At the wedding, Christine tells Stephen something quite hurtful; wide-eyed, he asks her how long did she have it in the barrel; a black partygoer walks behind him but is gone in the reverse shot. Moreover, she replies "Long time" and a couple walks past her, only to walk again past Stephen in the next shot.
Continuity mistake: When Daniel Radcliffe presents a special item he has put on white gloves, then a second later his gloves disappear. He no longer handles the item with gloves throughout the rest of the movie.
Plot hole: Vulture was able to re-create his suit despite the tech for it being confiscated when he was arrested. Also, the tech does not exist in the Venomverse, so he would have had no means of accessing it by any stretch of the imagination.
Continuity mistake: Towards the end of the movie, after the baseball game they go to the blue Chevy truck. One scene shows the blue truck with wheels from a Toyota Tacoma, then seconds later shows a different set of wheels on it.
Factual error: At the beginning they talk about an explosion in Istanbul but when they zoom out the location is the west coast of Saudi Arabia.
Visible crew/equipment: During the flashmob, there are people walking toward the camera while dancing on the street. The shadow of the steadycam filming the scene is left of screen.
