Well, if you had to formulate to make one of the most anticipated pilots of the entire pilot season, having Zach Galifianakis team up with Louis C.K. is a really good way to it. As part of his development deal, C.K. has done just that for FX/FXx.
There are no details as what the pilot might be, which makes us think that C.K. might be playing it so close to the chest that FX/FXx might not even know.
