I'm not sure why it would be a shock that Jude Law is a draw but Orlando Bloom isn't, you just have to look at their careers. Jude Law has been in an array of films, some successful ones too, and he has gotten nominated for an Oscar twice, and given a lot more of Oscar-worthy performances. Bloom hasn't done anything even remotely near what Law has done; he was in LORD OF THE RINGS, yes, also covered in a lot of make-up, and he hasn't done anything successful (maybe he has done something else, too lazy to look at his IMDB page right now) apart from that, nor has he proven that he is a great actor the way Law has. I don't think comparing him to Jude Law makes much sense in terms of their body of work or their star appeal; Law is a great actor who has been around for ages, Bloom is a moderately successful supporting player in a huge franchise.
