This. Along with Tom Baker, I grew up on Sylvester McCoy as The Doctor and for many years remained my second favorite Doctor. Troughton, Smith and McGann (via the audios) have recently surpassed him but his Doctor remains very special to me and I'm absolutely thrilled by this role for him.
I'm torn. I really like the guy who seems to be a nice and clever bloke, but to say the least, I've never warmed to his particular brand of acting and I've yet to find him convincing in any role. Maybe he'll be amazing in this, who knows?
