From The New York Post:
HBO’s new cable news drama by Oscar-winning scribe Aaron Sorkin will be called “Newsroom,” TV Newser reported Monday.

The series will follow the antics of the “News Night” staff at a fictional cable news network called UBS.

Actor Jeff Daniels will star in the show as news anchor Will McCallister, while English actress Emily Mortimer will serve as his executive producer.

“Law & Order” veteran Sam Waterston will appear as the network’s president Charlie Skinner.

“Together they set out on a patriotic and quixotic mission to do the news well in the face of corporate and commercial obstacles and their own personal entanglements,” according to a description from HBO.

Actresses Alison Pill, Olivia Munn and “Slumdog Millionaire” star Dev Patel will also appear on the show as newsroom staff.

No premiere date has yet been announced.

From Deadline:
It’s official: HBO has picked up Aaron Sorkin’s hourlong cable news network pilot to series. The now untitled drama (formerly More As This Story Develops), which has been a virtual lock for a series order, centers on a cable news anchor (Jeff Daniels), his new executive producer (Emily Mortimer), his newsroom staff (Alison Pill, John Gallagher Jr, Olivia Munn, Dev Patel, Thomas Sadoski), and their boss (Sam Waterston). Together they set out on a patriotic and quixotic mission to do the news well in the face of corporate and commercial obstacles and their own personal entanglements. The size of the order for the series is yet to be determined, but it should be around 10 episodes.
