Jack Slater is an action-film hero played by Arnold Schwarzenegger. An old projectionist (Robert Prosky) hands a magic movie ticket to Jack's biggest preteen fan (Austin O'Brien), and the kid steps right inside the latest Jack Slater film, becoming the actor star's sidekick in gunfights and car chases. But when Jack's nemesis (Charles Dance) gets his hands on the ticket, the fight busts out into the real world and Jack (à la Toy Story's Buzz Lightyear) refuses to believe he's a fictional character.
