HurtDoctor's quote "Great men are born in fire, it is the privilege of lesser men to light the flame" is a very un-Doctor-y quote, so this incarnation is clearly radically different from his antecedents and successors. Was he just "born" that way, or was he coerced to be that way?
Well it IS John Hurt. He's just got to have lots of cool and mysterious lines to say. It would probably be a bit weird to see him being all cute and quippy like the others.
