If I had auditioned for 'Merlin' on magic alone, I don't think I'd have got it. Like any kid, I probably had a magic kit, but it's not something I ever pursued. I've never watched a magic show like David Copperfield or used him to base my character on, but I really like David Blaine and Darren Brown. They are doing wonders.
