Channel Surfing: David Tennant Talks End of "Doctor Who" Run, Jeri Ryan Finds "Leverage," Noah Wylie to Battle Aliens for Spielberg and TNT, and More

Welcome to your Friday morning television briefing.

The Chicago Tribune's Maureen Ryan has an absolutely fantastic interview with Doctor Who star David Tennant on the eve of BBC America's airing of last Christmas' Doctor Who special "The Next Doctor." Among the topics of discussion: the end of his run on the legendary British sci-fi series, the truth behind the all-Doctors reunion rumors (false, says Tennant), and what's next for the actor (Poliakoff's Glorious 39), among other things. "I'm all finished," said Tenannt of his run on Doctor Who. "Three or four weeks ago, I filmed my last scene. So it's over. Still a long time to go before they're all broadcast, though, so I'm still clinging on for a bit. But yeah, it's done. It was very emotional, very exciting. We managed to go out with some of the best scripts I had in four years. So it was a real treat." (Chicago Tribune's The Watcher)

Jeri Ryan (Shark) has been cast in a recurring role on Season Two of TNT's drama series Leverage, where she will play "Tara, a smart-ass, street-wise con woman whom Sophie (Gina Bellman) calls on for help and who gets sucked into the Leverage family." (Hollywood Reporter)

It's official: Noah Wylie has signed on as the lead in TNT's untitled sci-fi pilot from executive producer Steven Spielberg and writer Robert Rodat. Project is set in a future where most of humanity has been wiped out by an alien incursion; Wylie will play the leader of a small human resistance force who are attempting to overthrow the occupying aliens.
