Greg Mottola has been tabbed to direct the HBO Aaron Sorkin pilot.Mottola

Helmer, whose current bigscreen pic “Paul” is playing in theaters, has plenty of TV experience, including working on HBO’s Lisa Kudrow series “The Comeback.” His other smallscreen projects include Fox’s Emmy-winning comedy “Arrested Development” and the net’s Judd Apatow laffer “Undeclared.”

Prior to “Paul,” his theatrical efforts were “Adventureland” and “Superbad.”

Pilot examines the behind-the-scenes look at a cable news network with Jeff Daniels in negotiations to star as the host of his own political show who, from the network perspective, can be difficult to handle. No other casting has been set.

In preparing the pilot, Sorkin spent time with a handful of cable personalities, including Keith Olbermann and Chris Matthews, to get a sense of what a typical day is like at MSNBC.

HBO debuted the five-part miniseries “Mildred Pierce” Sunday night and is prepping to roll out its highly touted fantasy drama “Game of Thrones” April 17.
