Larson has been trying to get his theatrical version off the ground for years, touting the idea at a fan convention called (and you must love this) KnightCon.
The network's official stance on this issue: NBC is unconcerned that any potential theatrical version will impact its series brand, a representative says.
That said, NBC's business affairs department is currently in talks with Larson about the show (cough-consulting producer credit-cough).
If they come to terms, this isn't the first time NBC Universal and Larson have worked out a deal to cooperate on a reimagined version of one of his classic series. Larson is the creator of the original "Battlestar Galactica" and holds a credit on the Sci Fi Channel version.
