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.
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.
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).
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.
Factual error: In the subplot on earth, the heroes' family members are trying to outrun the falling moon's gravity that's sucking everything into the air. So, naturally they duck into a barn, because, of course, gravity can't affect you behind a wall. And sure enough, behind the wall, they're suddenly safe.
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.
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.
Factual error: The deer in the forest somehow does not hear the giant dinosaur approaching, so doesn't run away. (01:21:10)
Factual error: The real bullet train from Tokyo to Kyoto only takes about 2 hours, rather than all night like the movie depicts.
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.
Suggested correction: The gloves don't disappear "a second later" but 2.5 minutes later, after many shots where his hands and even he himself are offscreen. He could have taken the gloves off anytime.
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.
Revealing mistake: When Gerard Butler is driving to the warehouse to find Frank, the speedometer and the rev counter are on 0.
Suggested correction: I could not see Will's speedometer or tachometer (RPM gauge) during his drive to Frank's. What I did see (and believe you saw) was the patrol officer's instrument panel while he was parked along the road using radar. This was before he pulled out to chase Will's speeding SUV, so both gauges should have been on the far left (i.e, on "0"). [00:46:28].
Continuity mistake: At the end of the last movie, Tails did not have the yellow small bag that he has in this one.
Other mistake: In the hot dog finger universe, everyone uses their feet for dexterous things, like playing the piano...but the pianos themselves are still designed exactly like our universe, at waist height where it's convenient for playing with hands, but very uncomfortable to play with your feet.
Other mistake: When Captain Collins climbs out of the water after falling in, her tank top is completely dry. (01:22:00)
Factual error: The parachute flare was not invented till 1922. This film takes place in 1918 but features one. (00:21:15)
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)
Factual error: When Danny and Sarah cut in front of the truck to take another route, there were at least 14-17 bullet holes through the rear window alone. Glass on that year of Mustang was not laminated and the bullets would have struck them. (01:27:35)
Continuity mistake: In Riri Williams' dorm room, the number of braids hanging over her shoulder changes frequently while Riri and Shuri are talking.
