Megamind (2010)

Continuity mistake: Whenever Megamind or Minion uses the disguise generator, their normal eye colour always show through their disguises, such as when they both disguise themselves as the Warden (the Warden has blue/gray eyes while Megamind has green and Minion has brown). However, during the final battle, Minion disguises himself as Megamind but he has Megamind's green eyes instead of his normal brown eyes.

Continuity mistake: While Megamind is in the Metroman Museum, he uses his dehydrator gun and turns Bernard into a little blue cube. He puts the cube in his pocket, then picks up Bernard's cellphone and glasses. At the end of the movie, inserted into the credits is a short scene where Minion is doing laundry. As he approaches the washing machine, Bernard pops out of it, having been rehydrated in the wash - with his glasses perched askew on his head. (00:30:05 - 01:28:20)

High Tech

Continuity mistake: When Megamind activates different "torturing devices" on Roxanne, She mentions about the spider and Megamind comes near her but that would be impossible because it wasn't shown that Megamind deactivated the Alligator trap.

Trivia: When Megamind as Bernard is in the library with Roxanne, the book he is reading ("Megamind Unmasked") has a description on the back of a self-help book entitled "The Happiest Me I Can Be". This is the same book that Metroman read (shown later in flashback) that caused him to decide to cease to be a hero. (00:43:30 - 01:08:30)

Trivia: When Metroman (voiced by Brad Pitt) makes his entrance at the museum opening, he walks in to the song from Elvis "A Little Less Conversation." This song is commonly played during the Ocean's 11/12/13 movies, in which Brad Pitt also stars. (00:10:00)

Trivia: During Megamind and Metroman's final battle in the beginning of the film, just after Megamind yells at Minion to fire the death ray, Metroman can be seen (from the crowd's point of view on the giant monitors) to fade out slightly from the observatory and fade in just behind Megamind's right shoulder. This corresponds to, and foreshadows, Metroman's flashback shown later. (00:17:50)

Megamind: You dare challenge Megamind?
Titan: This town isn't big enough for two super-villians.
Megamind: Oh, you're a villain all right. Just not a super one.
Titan: Yeah? What's the difference?
Megamind: PRESENTATION!

Roxanne Ritchie: So that's it then? You're just giving up?
Megamind: I'm the bad guy. I don't save the day, I don't fly off into the sunset and I don't get the girl. I'm going home.

Metro Man: We all know how this ends: with you behind bars!
Megamind: Oooh, I'm shaking in my custom baby seal leather boots!

Question: Throughout the film, Megamind transforms himself to take the appearance of other characters. Early on in the film, these characters are killed (or otherwise disposed of), allowing Megamind to take their appearance. Near the end of the film, Megamind takes Metro Man's appearance, but Metro Man is not dead (we see him as retired after faking his death, then specifically in the crowd scene at the Megamind museum opening). Is this an error, or is there some other reason why Megamind doesn't need to kill Metro Man to take his appearance?

Question: How is Megamind's robot able to do exactly what he does? We don't see him push any buttons or anything, so how is this possible?

Question: When Metro Man admits to Mega Mind and Roxanne what really happened at the observatory, he tells them that everybody had something he didn't have, which was a choice. What did Metro Man mean he didn't have a choice? He chose to become a superhero and use his powers to help people.
