Next on the Doctor's timeline (albeit appearing later from our point of view!) it's John Hurt. I was in two minds about this "by the way, here's an earlier Doctor we didn't mention before" storyline, but I say if you got a chance to cast John Hurt as the Doctor (or anyone else!) you'd have to take it. I did enjoy his withering put-downs of the daft boys who came after him, despite being technically far younger than them!
@simonabrett very nice!
