- Beam Me Up, Scotty!: For whatever reason, some people believe that Metroman says "Thank you, Random Citizen!" in his speech. He actually says "And I love you, Random Citizen!".
- Franchise Killer: This film ended theatrical releases of DreamWorks Animation films in Japan because it was released on the same weekend as the Tohoku earthquake and tsunami, becoming one of the lowest-grossing releases of any film in Japan. All further releases of the company's films in Japan have been Direct to Video until 2018, when Universal Studios (who bought DreamWorks back in 2016) released The Boss Baby there.
- Inspiration for the Work: The writers got the concept from the following question: What if Lex Luthor defeated Superman?

- Sequel in Another Medium: The video game continued the storyline from the movie.
- Stillborn Franchise: While the movie spawned two video games and a short, Jeffrey Katzenberg decided not to have future movie genre parody sequels including this franchise, Shark Tale and Monsters vs. Aliens.
- Throw It In!: The commentary reveals that a large portion of the jokes were improv, which isn't that suprising when you get Tina Fey, Will Ferrell, Jonah Hill, David Cross, and (to a lesser extent) Brad Pitt together.
- Metro City being pronounced Metrocity was due to a French screen writer, who pronounced it that way innocently, and they decided to run with it. Will Ferrell took it from there and started mispronouncing other words as well.
- Jonah Hill added in the line "And Megamind, this is for Space Step-Mom. You lied to her!" (originally the line was "And this one is all yours!")
- Tina Fey came up with "Girls! Girls! You're both pretty! Can I go home now?" when they were trying to figure out to cut the dialogue short.
- Trope Namer: The Power of the Sun.

- What Could Have Been:
- Robert Downey Jr. and Ben Stiller were approached to voice Megamind before the casting of Will Ferrell. Stiller would eventually go on to voice Bernard in the movie.
- The "Art of" book includes some of the things that never made it to the final cut, including a supervillain group, a giant lava monster, and concepts for Minion where his gorilla body was made from a real gorilla.
- The film was originally scripted as a live-action, R-rated, adult comedy. Megamind would have been called Master Mind, and Metro Man: Uberman, and Minion replaced three clones of famous historical figures. The studio did nothing with it, so it was brought over to Dreamworks Animation as a children's film instead.
- The directors originally wanted to play the film out with a cover of Michael Jackson's "Bad," until they realized that nobody could do better than the King of Pop himself, and the original was left innote .
- There was supposed to be a longer chase scene at the end, but they shortened it to keep their audience from getting sick.
- Megamind originally looked like◊ Galactus.
