Other mistake: Near the start of the movie Jon indicates that he has titanium in his right arm, but towards the end of the movie the bullet ricochets off his left arm. (00:08:55 - 01:34:45)
Other mistake: Lady Bird isn't finished talking about the present when the camera switches to the boy but in that shot her mouth isn't moving. Plus, right before that half her face is blocked out which sort of hides her realization face reaction. (00:17:05)
Other mistake: When Miguel is singing "Un poco loco" on stage, he goes out of range of the mic, but his voice is amplified.
Other mistake: During the yacht fire, only 3 people are saved, 2 dark hair girls and a guy (Councilman Rodriguez), but when on land, 3 girls are being questioned. Where did the blonde come from?
Suggested correction: The blonde was the one who Dwayne Johnson speaks too.
Other mistake: The airport assassination of Japanese dealer is claimed to be at 300 metres by Kincaid, but the camera shot shows the distance to be at least a mile.
Other mistake: At the beginning after the cab crashes, there is no damage to the car or the post.
Other mistake: When Rodrick and Greg bought groceries, there was one bag of "Cheez Curlz" and it ended up in the hot tub at the motel. They weren't shown buying another bag yet they had one when the pigeons "attacked."
Other mistake: When Captain Underpants falls in the Turbo Toilet 2000's mouth which has a liquid in it, he doesn't turn into Mr. Krupp.
Other mistake: When Ellen gets back to the inn after fetching the homeless guy, her coat has barely any snow on it when she enters. With the kind of snowstorm shown, she should have a ton of it. Same if not worse for Jake who came in before her. He has some snow on his arms, but none on his back - and he spent his time outside packing firewood with no time to wipe clean. (00:46:20)
Other mistake: When Boss Baby drools on the file at Puppy Co. he is not nearly close enough for the drool to hit the file.
Other mistake: The designer asking Khrushchev about what type of curtains they should have for the funeral. He first says "ruched" for the sample in his right hand and "not ruched" for the left. He then continues, but instead says "not ruched" for the right hand sample and "ruched" for the left. (00:59:30)
Other mistake: Anne makes the Oscar Wilde joke right before Bill kills himself, but he mentions it in the suicide note, which he obviously wrote long before.
Suggested correction: He wrote 2 letters, a longer one in the dresser drawer that he had spent time writing, and one that he wrote immediately before going to kill himself, explaining what he had done. The shorter one (referencing the Oscar Wilde joke) was written that evening while his wife was asleep on the couch.
Suggested correction: What evidence is there that he didn't write the suicide not that day?
It doesn't matter if he did, the point is he definitely wrote it before the Oscar Wilde joke. Right after the joke, he goes to the barn and kills himself. Anne is still on the couch, she hears the gunshot, she gets up and finds the note.
Anne is on the couch, then it cuts to him in the barn. He could have easily written his note between the two shots.
Other mistake: Towards the end of the movie when Spencer is riding the motorcycle to the top of the jaguar statue, he throws the grappling hook and swings on the rope. When Martha hands him the jewel as she falls, the rope he was swinging on disappears.
