Aaron Sorkin is back with another series set in the television world — HBO announced Thursday it has ordered his new hour-long pilot, about the adventures of a cable news show, to series.

This time, Sorkin’s story is centered around a cable news anchor, played by Jeff Daniels, as well as his staff and new executive producer. Emily Mortimer stars as the EP, and Sam Waterston returns after his long “Law and Order” stint to play their boss.

The premise of Sorkin’s untitled series, in HBO’s words: “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.”

Rounding out the rest of the cast, also known as the newsroom staff, is “Daily Show” correspondent Olivia Munn and ”Slumdog Millionaire’s” Dev Patel, along with Allison Pill, John Gallgher and Thomas Sadoski.

This is Sorkin’s third series about the land of TV — his short-lived 1999 comedy “Sports Night” followed the adventures at a cable sports network, while 2006’s even shorter-lived “Studio 60 on the Sunset Strip” focused on a late-night, “SNL”-esque sketch show.
