Harry Potter Naked

Well, Daniel Radcliffe to be exact. They are both the same person isn't it? It sort of spoils the image I have of the sweet and innocent Harry Potter. Read that he, Daniel, is doing a play in London called 'Equus' by Peter Shaffer. Not only that he will be naked, the character he plays blinds six horses with a hoof pick. Definitely not my cup of tea. Isn't he only 17 or something?
