Trivia: While a sequel was rumored for years, series creator Brad Bird has stated that he would only make an "Incredibles 2" if he could come up with an idea that he felt was just as good as the original. It took 14 years for the film to finally be released - the longest gap between a Disney/Pixar film and its sequel.
Trivia: Due to the long time between the first installment and Incredibles 2, two actors had to be replaced; Spencer Fox, who played Dash, was replaced by Huck Milner due to Fox's voice breaking and being unsuitable for the role, while Jonathan Banks replaced Bud Luckey as Rick Dicker, due to Luckey's passing.
Trivia: The film "Dementia A-113" on the theater is a Pixarified reference to the Francis Ford Coppola film "Dementia 13".
Trivia: The film shows the first use of a gun by a lead character in any Pixar film, when Elastigirl shoots the door lock.
Trivia: When signing the International Superhero Accord, all the Ambassadors, save Henrietta Selick, are name of various crew members that worked on the film. For example, Alan Broiler was the supervising animator. That said she's clearly a reference to Henry Selick, a graduate of California Institute of Arts like director Brad Bird, who went on to direct The Nightmare Before Christmas and Coraline.
Trivia: Mr Incredible's coffee mug is from Insuricare, where he worked in the first film. You can see it when he is learning Dash's maths homework.
Trivia: The shot with all the super heroes after they stop the yacht resembles the Justice League ending footage.
Trivia: The jar of bullets which bounced off Bob from his study in the first movie are visible in the boxes of saved junk from the old house.

Trivia: The film opens with the entrance of the "Mole man" digging up of the city as reference to Fantastic Four #1 from a 1961 Marvel comic book.
Trivia: The Chinese food boxes are also seen in several pixar movies - Ratatouille, Inside Out, A Bug's Life, and Toy Story 2.
Trivia: At 118 minutes, "Incredibles 2" is the longest computer-animated film ever made.
Trivia: The way Elastigirl opens the door in Screenslaver's place using her hand resembles Mr. Fantastic in the 2005 Fantastic Four film.
Answer: I think the fact that Evelyn from Incredibles 2 and Roxanne from Megamind bear some similarities is purely coincidental. The idea that there may be a hidden connection between the two is unlikely and the idea of them being related is even more unlikely. It should be noted that Incredibles 2 is a Pixar production, and Megamind is a Dreamworks production, so the two aren't even made by the same company. Perhaps, her design was inspired by some features of Roxanne, but the idea of the two being connected or related is pretty doubtful.
