David Tennant was interviewed by Catherine Tate in the BBC radio show Chain Reaction tonight, and you can listen to it here for the next 6 days, no matter what country you live in. (Click "Listen Again to the latest edition" in the righthand column.) If you're a Doctor Who fan, it really is worth listening. It's always such a joy when one of my favorite actors on-screen turns out to be funny, smart and charming in real life. I listened to the interview earlier tonight (while knitting), and it made me so happy, I got excited all over again about Season 4, even though all sorts of pre-revealed plot elements have made me nervous about that season. No matter how much I might worry about (or even hate) some of their decisions in this coming season, still...Doctor Who!
