Tenth Doctor David Tennant appeared on the Nerdist Podcast with Chris Hardwick talking about Life, The Doctor and Everything.
From the description:
Yes! The 10th Doctor himself, David Tennant, in a sit down chat with Chris in a very posh English library! This is the full unedited audio from the segment on the Nerdist TV show (originally aired 12/24 on BBC America, probably available on iTunes now). Chris and David chat about Doctor Who, Harry Potter, The Incredible Hulk, and working shirtless. PLUS! MANY fan questions answered. He was nine kinds of awesome. You asked for him (so did I)! Here he is! Now enjoy this Scottish burrito (which sounds like a filthy sex-thing but it isn’t)!
