PLEASE. Yes, one word. Coming from Josh Radnor, the film made the 2007 Black List (the best unproduced screenplays of the year). They seemingly joined the cast since “Production Weekly” doesn’t have the best track record with casting information so take it as a sorta confirmed rumor. And it only appears to be a romantic comedy because, really, with a goofy title like that, what the hell else could it be? It’s not a post-apocalyptic thriller about being insatiable, now, is it? Whatever it is, Mara’s in it so it’s all good.
