Deep Thought

I was thinking that the current Doctor, Peter Capaldi, was the oldest doctor, was the oldest actor to play The Doctor, (Do we capitalize the "The"?) and then I realized that John Hurt, at age 73, as [T]the Doctor, albeit a Doctor who never had a bit on the series.

So, is Peter Capaldi the oldest actor to play [T]the Doctor, or is it John Hurt, who played [T}the Doctor who did (or didn't) destroy Gallifrey?

I'm curious here, but I figure that I am stirring up a sh%$ storm, but I am alcohol loading for the new year, so I do not care.
