Plot hole: Spoiler. Agent M points out as highly suspicious that the twin assassins knew the location of Vungus, and High T backs her up on this, saying that only a handful of MIB officers could have leaked that information. High T also established that those aliens were part of the Hive collective. It turned out that they were not part of the Hive, and the Hive connection was made-up entirely by the villain himself...which is the Hive! What he did was absurdly counterproductive to his cause: nothing except the report he himself made up connected the Hive at all with the case.

Continuity mistake: When Tim and Lex first arrive, Lex is wearing a purple tank top with a colorful design, and in the following scenes or even between consecutive shots her tank top changes to completely different designs, though it's the same style of tank top.

New this month Factual error: In the beginning of the movie, while dancing with the sign, the guitars in the window of the music store are D'Angelico guitar designs that weren't released until the 2010s.

Natalie: Hello, David. I mean "sir." Shit, I can't believe I've just said that. Oh, and now I've gone and said "shit" - twice. I'm so sorry, sir.
Prime Minister: It's fine, it's fine. You could've said "fuck", and then we'd have been in real trouble.
Natalie: Thank you, sir. I did have an awful premonition that I was going to fuck up on the first day. Oh, piss it!

Trivia: When the oldest boy is hit in the face with a basketball, he blurts out "Oh, f***!"

New this month Question: I don't understand Max's punishment. In the ending, Max says "a month in the hole", but his father tells him that birthdays, holidays, and summers are cancelled. He also tells his son that "the devil lives inside him", to no longer call him "Dad", takes away his electronics, locks him in his room, and says that he will always love him, but no longer likes him. So, is Max grounded for life or is it "a month in the hole"? Are his birthdays, holidays, and summers really cancelled? And does anyone else find this ending to a comedy actually depressing because of the way Max's father treats him in the end?

Visible crew/equipment: A reflector screen is visible on Hawkeye's sunglasses at the very end when Thor and a restrained Loki are returning, presumably, to Asgard. (02:06:10)

Continuity mistake: As Flik is just leaving the island to go find the "tough bugs", he's followed by two young male ants. The two young ants look quite different, one being blue and the other more purple. The blue one says "My dad gives you one hour before you come back crying" and the purple one says something to the effect of "My dad says you're gonna die". But after Flik has hit himself on the rock whilst trying to cross the valley, the purple ant says to the blue ant, "Your dad's right, he's gonna die". Wrong ant.

Continuity mistake: When Taran, Princess Elonwy and Fflewddur try to escape from the Horned King's castle, Taran opened the gate by removing the chains. The next shot the gate is closed and chained, the last shot the gate is open again, and the boat is pushed trough by Taran. (01:06:33)

Revealing mistake: When Qui-Gon, Jar-Jar, and Padme are eating at Anakin's house, Anakin's mum pours water for Qui-Gon. But when she gets to Jar-Jar, she tips the pitcher but no water comes out. (00:39:10)
