Philip Seymour Hoffman, who was found dead in his apartment of an apparent drug overdose today, had been poised to take on his first leading role in a television series in "Happyish," an original Showtime comedy. He was set to play Thom Payne, a 42-year-old ad exec working for people half his age at a company where "digital" and "social" get thrown around more often than he'd like. The series, which was created by author and "This American Life" contributor Shalom Auslander, received a series order last month.

Only the pilot, directed by John Cameron Mitchell, has been shot -- with the series reportedly built around Hoffman, its future is very uncertain. A clip from the episode was previewed at the Television Critics Association press tour in January to much positive response.

Showtime's released the following statement about Hoffman's passing:

Philip Seymour Hoffman was one of our generation's finest and most brilliant actors. He was also a gifted comedic talent. It was a great privilege and pleasure to work with him and we are all absolutely devastated by this sudden loss. Our thoughts go out to his family at this very difficult time.
