Outgoing Doctor Who producer Russell T. Davies and outgoing Doctor Who star David Tennant gave a 20-minute exit interview on Boing Boing Video (via YouTube). The entire video appears after the jump if you're feeling too lazy to click the link.

The interview took place around the San Diego Comic Con and is being done as a promotion for the next Doctor Who special, The Waters of Mars. There are a few spoilers (they do reveal the Master's appearance in the final episodes later this year, but that's pretty common knowledge at this point), but there is a sense of the feelings from the dynamic duo as they leave the franchise.

I like how host Richard Metzger calls them out on how they talk without actually saying anything. Of course, they follow up in typical British fashion with an intellectual justification for their "caginess."

They even asked David if he'd come back to the role for a multiple Doctors story, but I was disappointed they didn't ask any question about the potential for his participation in Big Finish audios. Oh well. Here's the video.
