Channel Surfing: Chuck Renewal Prognosis Improved, Sarah Wayne Callies Hunts The Walking Dead, Conan, Castle, and More

Welcome to your Monday morning television briefing.

Could it be that things are looking up for Chuck? Deadline.com's Nellie Andreeva breaks down the current on the bubble series at the broadcast networks, including NBC's Chuck. "Last year, NBC’s Chuck got an 11th hour reprieve, clinching a partial 3rd-season order on Sunday afternoon before upfront week," writes Andreeva. "This time around, its fate will be decided earlier if the show’s producers get their way. Several days ago, creators Josh Schwartz and Chris Fedak pitched NBC their vision for Season 4 and producing studio Warner Bros asked the network for a quick resolution so the series could keep its writing staff. Even with NBC brass happy with their drama development, the spy dramedy’s chances of renewal are considered very good -- and certainly a lot better than last year when a sponsorship deal with Subway sealed the renewal. With the show rising in the ratings this week and fans staging rallies tomorrow, Chuck may be one solid ratings performance... away from an early renewal."

Meanwhile, today marks the day for the multi-city Chuck flash mobs, but if you're not in one of the cities participating, don't fret: you can still show your support for a fourth season of Chuck by participating in the Twitter mob scheduled for today between noon and 1 pm Pacific Time. Sample tweets include: "@NBC – We want more #CHUCK! Give us another season of flashes and fun. The world’s safety depends on it! #FlashChuck" or "#CHUCK rules! @NBC show your love for CHUCK and the fans will show their love back. We want a 4th season! #FlashChuck" (ChuckTV.net)

The New York Times's Bill Carter talks to Jeff Gaspin's efforts to pull NBC's schedule "out of a long, precipitous slide," the network's development slate, and the C-word: Conan. "Late night’s not my problem anymore," said Gaspin, referring to Conan O'Brien's move to TBS. "I don’t have to worry about Conan anymore. Whereas if he was on Fox we’d all be, you know, what’s it going to do? That’s all over. The Conan story is gone for me." (New York Times)

E! Online's Kristin Dos Santos talks to Nathan Fillion about the upcoming season finale of his ABC procedural drama Castle. "Beckett has set her eyes on another man, and it's really getting to Castle," Fillion told her. "He's really not having an easy time with it, so we're getting to a point in time where she's gotta make a choice. And he's gotta make a choice! There's gonna be a choice made. An emotional choice. It's an emotional cliffhanger." (E! Online's Watch with Kristin)

The Chicago Tribune's Maureen Ryan has a brand new interview with "A Song of Fire and Ice" novelist George R.R. Martin, whose fantasy novel series is the basis for HBO's upcoming series Game of Thrones. (The series itself is undergoing some cast changes at the moment: Jennifer Ehle was replaced by Michelle Fairley and Tamzin Merchant--who played Daenerys Targaryen--will be replaced as well.) "I knew that the limitations of budgets and the censorship limitations," said Martin about possible television homes for "A Song of Fire and Ice," ruling out the broadcast networks. "I know it’s loosened up some since I was active in the ‘80’s and ‘90’s, but I can still remember the fights with Standards and Practices and censors about the sex and violence. And the books are full of sex and violence. I didn’t want some watered-down, bowdlerized version of this... [HBO] had done shows like Deadwood and Rome and The Sopranos and that was the kind of thing I saw this as." (Chicago Tribune's The Watcher)

E! Online's Megan Masters has an interview with Vampire Diaries star Matt Davis, in which the former Damages co-star talks about why his Alaric is in need of some steamy sex scenes on the CW supernatural drama series. "We decided that the best way to reconcile them is a ménage à trois," Davis said, joking, about the return of Alaric's wife Isobel. "No, it's shocking. To see this missing wife of his after so long. Not only is it shocking, but those moments never go the way you expect them to. His whole life changed when she vanished, and he's been searching for her ever since. [To] finally confront the thing he's been looking for? That would turn your life upside down, and it will definitely be a big moment for Alaric." (E! Online's Watch with Kristin)
