The new 10-episode series "Billy & Billie"follows a couple — played by Adam Brody and Lisa Joyce — as they fall in love. In true Neil LaBute fashion, there is a catch. The two just so happen to be stepsiblings. LaBute writes, produces and directs the series which debuts March 3 on DirecTV at 8:00 PM Eastern and Pacific time. Read the Playbill story.
