Now this is interesting: Fox has optioned Lev Grossman's "The Magicians" with the intention of adapting it into a television series. Fantasy seems to be big on the networks' radar since the first season of "Game of Thrones" did well and earned a pile of Emmy nominations. Wil Weaton tweeted his interest in being cast, without stating a specific role. He might make a decent Quentin Coldwater.
However, this whole thing strikes me as odd. I'm not sure anyone but HBO would have the budget to pull it off, let alone allowing the necessary creative freedom. The home of "American Idol" and "Glee" seems like a strange home for a dark, adult serialized fantasy series. (Not to mention, the characters aren't exactly the sort of people you root for.)
Would they try to squeeze the entire book into one season? If so, any series would be short-lived because, as of right now, Grossman has written only two Fillory-related books. Or would they take the True Blood route and let the writers go their own way with it? And the biggest question of all: Will this really come to fruition and reach the small screen?
