Back in 2001, a 12-year-old Rupert Grint was perfectly cast as Ron Weasley, Harry Potter’s redheaded, lovably insecure, comic-relief sidekick who, over the course of eight movies, develops into a skilled wizard, capable Quidditch player, and even something of a heartthrob. Grint’s real-life transformation has been no less dramatic. In this slideshow, we track the actor’s onscreen and red-carpet appearances, from Sorcerer’s Stone all the way through Half-Blood Prince.
