Other mistake: At the end of the film when they arrive in NYC looking for the library, we know that they survived because they are inside with a roaring fire burning. But where is the smoke up above, as Jack Hall approaches? There must be a chimney, or else they would have all died of asphyxiation.
Other mistake: At the end, when Peter saves Mary Jane from the collapsing structure, he jumps up in the air and swings her to safety. However if you look at the web he is holding onto it is hanging down vertically. What did he attach the web to that was directly above him, the sky? Every bit of the structure around him was/had collapsed and the only thing remotely close to swing from was the cranes. Yet we see that was quite a distance away, so Peter would have had to shoot the web away from himself not above him. (01:47:50)
Other mistake: At the very end, when a man is painting the "F" of the city's new name on the water tower, with white paint, you can see that though the brush is white, and it is touching the surface of the water tower, no paint is left on the surface of the water tower. Nevertheless, the painter continues painting the letter in the next shot, even though no paint is left on the surface. (01:36:00)
Other mistake: Wouldn't Thunderbird 1 leave some sort of burn marks on the pool side as it lifts off? The blast pattern is close enough to the sides.
Other mistake: When Polly notices the reflection of Joe's airplane marking on the water, the code "hllod" gives "Polly." That's impossible. To get "polly" from "hllod," a person would have to rotate the word 180 degrees, not view it as a mirror reflection.
Other mistake: Near the end of the film when Jack-Jack is manifesting various abilities, his first display is of the human-torch-type of superpower. This would have burned away all of his clothing, yet (for obvious reasons) his diaper remains intact. This is particularly apparent as designer Edna Mode's costume for Jack-Jack was earlier shown as fire-resistant, but he was not dressed in his outfit during this scene. (01:44:15)
Suggested correction: This is definitely intentional, not an error. We see Jack-Jack use his fire powers without burning his diaper in Incredibles 2. Having fire powers without burning clothes is just a retcon.
Other mistake: When the sun comes up over the mountains on Crematoria, it shines full view on Riddick's face and makes his goggles see-through. You can see Riddick's eyes without the contact lenses used to represent his nightvision.
Other mistake: When Evan finishes talking to the "prostitute Kayleigh" on the restaurant, he goes to his room, which finds his friend having sex with a girl. When Evan demands them to leave the room, he sits on the chair, and opens his diary, but you can see that when he opens it, the pages are empty. He doesn't turn to another page before he begins to read, so he appears to be reading from the blank page.
Other mistake: When Robin Williams starts to download Banister's life files the computer says there are 544,628 hours of footage (approx 62 years) yet shortly after a newspaper headline states that Banister died aged 54.
Suggested correction: As already corrected, just because we can't see an outlet for the smoke doesn't mean there isn't one. White smoke against white snow is very hard to see.

But they were still burning the books, which meant the smoke should be black, if they stop burning the books, the smoke would have been white, which isn't the case in the movie.
Just looked at a boatload of videos of burning books, including one in a fireplace, and the smoke was indeed white.
