Daniel Radcliffe
There’s no denying that the actor for the titular role was the most affected by the franchise’s success, but not always the positive kind. While Harry Potter is still a book, Daniel Radcliffe is already making films with the TV movie ‘David Copperfield’ and ‘The Tailor of Panama’. After auditioning several times, Radcliffe got the role, and as the famous story, he received the call while he’s on a bath. After the life-changing role, Radcliffe took roles that were often different from Harry Potter, and this technique proved his versatility and range. Unfortunately, Radcliffe faced substance problems while filming the series, but since then sobered up. He continues to take on game-changing roles, most notable are his characters in ‘Horns’ and ‘Swiss Army Man’.
