Released on November 16, 2001, Harry Potter and the Sorcerer's Stone (based on the uber-popular J.K. Rowling book series) changed movie history forever. The debut installment of the billion-dollar franchise was a family-friendly film starring a precocious preteen as an orphaned boy wizard, who started a new breed of rabid movie fans across the globe. Going through an awkward phase during puberty is painful enough, but growing up on the big screen? "It's always a bit embarrasing," Daniel Radcliffe told Entertainment Weekly. "I was 11 (when I started)," he recounted. "And I'm not going to look back on it and say I'm not proud of it, 'cause I am. But it's like seeing baby photos of yourself."
