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.
Character mistake: It is incorrect to say someone who controls technology a "technopath." The -pathy suffix denotes the "ability to feel." It would've been more correct to say "technokinesis" as the suffix refers to movement, ie. Telepathy vs Telekinesis.
Suggested correction: Technology controllers are always commonly called technopaths.
Character mistake: When Will is in the nurses office she sues her eyes to X-ray his chest. She says that she doesn't see any broken bones but look closely at Will's ribs. They are actually broken.
