Trivia: The scene where Frozone, voiced by Samuel L. Jackson, has a cop pointing a gun at him, where he wants to "get a drink of water", is very similar to the scene he plays in Die Hard with a Vengeance, where he is in the same situation in the subway platform, needing to answer a pay phone.
Trivia: Other supers from the movie that mimic comic book heroes (disregarding gender): Psycwave is Professor X, Phylange is Banshee, Blazestone is Pyro, Thunderhead is Storm, Gazerbeam is Cyclops, Apogee is Sunspot, and Gamma Jack is Ultraverse's Atom Bob. Jack-Jack also briefly manifests the powers of the Human Torch and the Incredible Hulk and the board that Frozone uses near the end is reminiscent of the Silver Surfer.
Trivia: The film's creators originally couldn't find an appropriate actress to voice Edna. Finally, when asking actress Lily Tomlin to voice Edna, Brad Bird provided an example of what she should sound like. Tomlin told Bird that he had nailed the voice well, and said that Brad should do the voice himself.
Trivia: Originally, an old man named Snug Porter was going to fly the plane that Helen flew to Syndrome's HQ. In the first script the favor she called in for was for him to fly her to HQ, not just lend her a plane. When the explosion blew up the plane it was implied that he didn't survive. They cut the scene because they couldn't give him enough screen time to make the audience sad when he died. You see one shot of him when Elastigirl picks up the photo while she is on the phone. He is also in the background of the wedding scene. The entire cut sequence can be seen in its basic storyboard form on the DVD extras.
Trivia: Craig T. Nelson is the voice of Bob Parr. When he accidentally breaks the car door and mutters to himself, you can hear him saying "Oh geez." This was written in once Nelson was cast as Bob Parr, as this is a phrase of frustration commonly used by Nelson's character on the "Coach" show.
Trivia: The main characters' powers have counterparts in the Marvel and DC comics: Mr. Incredible has super-strength and invulnerability like the Incredible Hulk (though with more brains); Elastigirl is the female version of DC Comic's Elongated Man (or Marvel's Mr. Fantastic); Dash with his power and uniform resembles the Flash; Violet has the basic powers - invisibility and force field generation - like Marvel Comic's Invisible Woman; and Frozone resembles Iceman, at least in the use of his powers.
Trivia: The kid on the tricycle is an inside joke representing the real life personality of John Lasseter, the chief creative officer at both Pixar and Walt Disney Feature Animation. During production of his films, he is usually waiting for something amazing to happen in regards to the animation or special effects, and later (during production) has been heard several times to remark of such amazing results as "totally wicked".
Trivia: Some of the characters in this film bear visible likenesses to other famous villains. Bomb Voyage, the french villain at the beginning, looks almost exactly like the Joker, and the Underminer at the end of the film acts and appears in almost exactly the same way the Mole Man did in the Fantastic Four comic books.
