Inspired by his love of comic books, high school student Dave Lizewski (Aaron Johnson) decides to transform himself into a masked crime fighter -- a decision that eventually thrusts the teenager into Internet stardom. Soon, Dave's antics inspire a wave of would-be heroes to don costumes and live out their superhero fantasies. Nicolas Cage, Christopher Mintz-Plasse and Chloe Moretz also star in this comic book adaptation from director Matthew Vaughn.
