A great actor and massive fan of the show, and older doctor as well, great great news!! Hope he keeps his Scots Accent, and I can defintely see him bringing more of a darkness to the character...I wonder at 55, how he will cope with the contratual 'running down similar looking corridors repeatedly' scenes...
Good Luck Mr Capaldi!!
I have got to admit though...its going to be a little hard to forget his other role as a doctor in The Thick Of It...
