Here's an American one for ya: Superhero Movie, starring one of the best actors from Nickolodeon, Drake Bell, as a teenager who gets bitten by a Dragonfly, and gains superpowers while being advised by his uncle Albert, played by Leslie Nielson.
As he gains wisdom and advice from other "well known" superheroes, he goes to the mutant academy. While there, the Professor's wife catches the Invisible Girl, played by Pam Anderson, in his closet.
