Character mistake: Diana categorizes without a doubt Aquaman as "a mixed blood" Atlantean because Bruce tells her that he could breathe air. However Steppenwolf interrogated one of the guards from Atlantis on the ground, and he could breathe just fine.
Character mistake: At the start Wonder Woman stops a terrorist attack in London, and one of the terrorists tells her the bomb will flatten 4 blocks. This must be true as she is using her lasso of truth. But she just throws the bomb through the roof window and it explodes without damaging anything. A bomb with that blast radius would still damage nearby buildings, whether it detonated in the air or on the ground.
Suggested correction: You are compelled to YOUR truth. He didn't build the bomb. He could have been wrong based on what he knew. Otherwise, why did the terrorists have to go through all that trouble to plant a bomb there if they could level 4 blocks just by planting it outside in the car.
Which is why it is labeled a character mistake, yes. You are right in your observation, but at the same time, the only truth the movie feeds us by exposition is that the bomb is supposed to have a certain power, and that is not true. Movies tend also to use this trope/trick a lot; the moment you throw a bomb at 'the last second', the explosion that was supposed to be uber-powerful is relatively harmless, even when the distance was not all that significant.
Depends on how high she threw the bomb. She can throw that thing high enough that it won't cause damage. Certainly if it's not as powerfull as the terrorist thought.
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: When in the mineshaft Trevor says that magnesium is used in gunpowder. That is not correct.
Character mistake: The poster on the wall near the start reads "Our Egg Donor's [sic.] are helping to fulfill the dreams of women across America." There is an unnecessary apostrophe in the word "Donor's." (00:10:05)
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: Before the junk man drives away he calls Mr Coggins "Bill." The correct first name is George.
Character mistake: When John Henry Irons is arrested, two police officers lay him face-down in order to zip-tie his wrists behind his back. A close-up of Irons' hands, however, reveals that the zip-tie only wraps around his right wrist while crossing about mid-way on his left thumb, meaning that he could easily remove his left hand from the restraint with very little effort. Arresting police officers would never make this mistake in real life.
Character mistake: During the military parade, check the lady behind the soldier on the left. She can't help stare at the camera the whole time before the soldiers arrive. (00:07:03)
Character mistake: When Tom goes into cardiac arrest, the doctor uses the defibrillator paddles on him, but she uses them whilst the hospital gown is still on him. A defibrillator must be used on bare skin if the electricity is supposed to get through to his heart. (01:08:55)
Character mistake: When Princess Mombi is sleeping she is snoring, but she has no head.
Character mistake: When Hook has Pan under control, the kids start to say "I believe in you" in turns. The second one, a red haired boy, can't help staring at the camera.
Character mistake: They keep calling the vehicle a milk truck but it says "ice cream" on it. (00:23:55)
Character mistake: Pygar says to Barbarella, "An angel has no memory." If that's true, how does he recognise Barbarella's touch, her name, his name, his nest, everything?
Character mistake: Given Billy still remembered and recognized him it seems strange Kate doesn't when she mistakes Daffy for Gizmo.
Suggested correction: Billy spent significantly more time bonding with Gizmo in the first movie - days and days. By contrast Kate had very little actual time with him.
Character mistake: When Harry takes the kids to his business, he's showing them how he "restores" cars. After putting the bumper on, Harry says, "Transmission. The sawdust quietens the gears and let's the engine run as sweet as a nut." Putting sawdust into the transmission would not change how the engine runs as they are two separate components. It may make the transmission quieter but would have zero effect on the engine.
Character mistake: The registration number of the stolen van is GPW729 but every time it mentioned in the dialogue it is stated as GPW927.
Character mistake: Pretending to be a witch, April says that the song the walkman played was obtained because "I shrunk four incredibly cool guys and I locked them in there." The Barrio Boyzz were five at the song's release. Did she let one Barrio boy go? Was one of the Barrio Boyzz uncool? (00:16:40)
Character mistake: Inside the loop Barron said the only thing he can't change/shape shift is his eyes but when Emma and Enoch rush in Barron is able to change his whole body, including his eyes.
Character mistake: Big Ben is loaded feet first into the ambulance, he should've been loaded head first.
