I have to steal from someone.

-David Bowie, Hugh Laurie

One I just thought of:

-Cillian Murphy

If you want a black actor, Paterson Joseph--who was high, high up on the list for this round anyway--is stupendous, & I think would have made an excellent doctor. He is on the snarky-side of smart (or at least that's what I've seen of him), he is British, & he is hilarious.

Just my twopenny. :)

I've seen Ian McKellen on quite a few, and I just think he's too old. I love him, and think he's amazing, but he just doesn't scream "Doctor" to me. Same with Anthony Hopkins.

James McAvoy is gorgeous and again, love him, but I don't think he'd do "Doctor" well. I could be wrong. He'd probably still be better than this new dude they've got cast.

The Doctor's always been a little bit goofy and quirky, so it's also important that he be able to play the comedic angle as well.

I can't imagine Judy Dench as The Doctor, but it could be funny to see her try.
