Entertainment Weekly's Michael Ausiello talks to Spartacus showrunner Steven S. DeKnight about the two options available to the production and pay cabler Starz in light of series lead Andy Whitfield's cancer relapse. “The two main options are to close up shop or recast,” DeKnight told Ausiello. “I want to talk to Andy and find out how he feels about the options. That’s obviously very important to us... We’re still absorbing what’s happened. I think it’s going to be a little while before we reach any conclusions.” (Entertainment Weekly's Ausiello Files)

E! Online's Kristin Dos Santos is reporting that Darren Everett Criss (Eastwick) has been cast on FOX's Glee, where he will play Blaine, described as "a gay student from a rival school glee club named the Dalton Academy Warblers." While some might leap to the judgment that Criss' character will be the love interest for Chris Colfer's Kurt, Dos Santos cites an unnamed source who says that isn't the case: "Although people might speculate that this might be the possible boyfriend for Kurt that Ryan has talked about, he is fairly sure that this particular character won't be. This friendship will be platonic." (E! Online's Watch with Kristin)

Former Heroes star Zachary Quinto is bummed that there won't be a two-movie to wrap up the superhero drama's dangling storylines after NBC axed the potential wrap-up. “It’s disappointing that there was such a lack of resolution,” Quinto told Entertainment Weekly. “But unfortunately that’s just the nature of network television….Nothing really surprises me in terms of network and studio bureaucracy. It’s the way it goes... If it was in their best interest I’m sure they would have done it. And for whatever reason, they didn’t think it was. So that’s a bummer. But we have to just accept it and move on.” (Entertainment Weekly's Ausiello Files)
