Showbiz CV: Rupert hadn't done any professional acting before he won the role of Ron Weasley in the Potter films. But he had his fair share of school plays under his belt including playing gangster Rooster in Annie, Peter Pan and Rumplestiltskin in the Grimm Tales.
Rupert spotted his chance to audition for Harry Potter after the casting director made an appeal on Newsround. For the audition, Rupert made a video tape of himself performing a rap he had written explaining why he was perfect for the role of Ron Weasley.
Potty about: Jim Carrey movies. Rupert loves all his movies, especially Ace Ventura, The Mask and The Grinch. Rupert also loves chemistry lessons at school. "You get to make potions and stuff. It came in handy in the movie," he says.
Movie magic: Rupert's favourite scene in Harry Potter and the Sorcerer's Stone was the invisibility cloak. He also loved the chess scene - "it's bloody brilliant!" he says.
If he really had magic powers he would... want 'to levitate' says Rupert.
