Character mistake: In the scene where Steve and Josie prepare to leave to fight the giant robot at the beginning of the movie, Steve tells Will "Oh, Will, a reminder: a lot of the kids at Sky High will only have one super hero parent, not two." When he says "one super hero parent", he holds up two fingers. When he says "not two", he holds up only one finger.
Trivia: In 1975 Kurt Russell starred in a Disney movie titled "The Strongest Man in the World" in which he played Dexter Riley, a Science student that invents a formula that gives him super strength. Thirty years later he co-stars in Sky High (another Disney movie) playing Steve Stronghold / The Commander, whose power is once again super strength and is the father of the main character, Will Stronghold, who also has super strength.

Trivia: Check out the "Aquabats" poster in Will's room. The Aquabats are a band that sing silly songs, while dressed in super-hero outfits. They do this for their videos as well as on stage. A funny little nod to the fact that a super-hero kid would like a band that dresses as super-heroes.
