Continuity mistake: At the end of The Incredibles, when the Underminer shows up, the Parr family don their masks but are still in their civilian clothes, though Bob is about to take off his shirt. At the beginning of Incredibles 2, in the flashback, as soon as the Underminer appears, they appear in their super suits. Also, the Underminer leaves out "I hereby declare war on peace and happiness! Soon all will tremble before me!" (02:00:00)

Continuity mistake: When they have rolled all the weed together, Dante lit the bong with both of his hands on the bong, but in the next shot he is just sitting back on the couch.

Col. Nathan R. Jessep: Son, we live in a world that has walls and those walls have to be guarded by men with guns. Who's gonna do it? You? You, Lieutenant Weinberg? I have a greater responsibility than you can possibly fathom. You weep for Santiago and you curse the Marines; you have that luxury. You have the luxury of not knowing what I know: that Santiago's death, while tragic, probably saved lives and my existence, while grotesque and incomprehensible to you, saves lives.
You don't want the truth because deep down in places you don't talk about at parties you want me on that wall, you need me on that wall. We use words like honor, code, loyalty. We use these words as the backbone of a life spent defending something. You use them as a punchline. I have neither the time nor the inclination to explain myself to a man who rises and sleeps under the blanket of the very freedom that I provide and then questions the manner in which I provide it. I would rather you just said "thank you, " and went on your way. Otherwise, I suggest you pick up a weapon and stand a post. Either way, I don't give a damn what you think you are entitled to.

Trivia: The tune that Elle Driver is whistling in the hospital is the theme from the movie 'Twisted Nerve' (1968)

Question: What was that scream at the end? Was that Kate's scream? If so, why did she scream? What happened to her at the end?

Factual error: In the final fight scene with Malekith, Thor falls through a portal that brings him to Charing Cross station, where the lady on the train tells him he has to ride 3 stops to get to Greenwich. Charing Cross is not on the Jubilee Line and so not directly connected to Greenwich - even then it's a lot more than 3 stops. (01:33:45)

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: Just before Flynn cuts off Rapunzel's hair, there is a shot from behind him and he reaches up with his right hand to push her hair behind her ear. His arm is visible up to his forearm and the shackle is nowhere in sight. However, in the next, wide shot, the shackle is suddenly up around his wrist. (01:01:20)

Plot hole: When the inspection team goes into the Rogue One shuttle and then the Rebel team comes out of the shuttle in the inspection team's disguise, no one near the landing pad or in the building notices that two stormtroopers have disappeared from the group, the Imperial Officer has grown a beard in less than 5 minutes, and an Imperial Droid has come into the group.
