Former DR. WHO star PETER DAVISON disapproves of plans to cast Daniel Radcliffe in the hit TV show, fearing the young actor will turn it into a mockery. Davison - who was 29 when he took on the sci-fi role in the 1980s - claims the Harry Potter star is too immature for the role and will attract too young an audience. He says, "What's wrong with there being an older doctor? I don't think that such a young man would be a good idea - it might end up like a children's show."
