'The Newsroom' Season 2 Teaser: HBO Releases Sneak Peek (VIDEO)

"The Newsroom" is gearing up for Season 2 and now, HBO has released a teaser (above).

Although nothing is really revealed in 36 seconds of switch-flicking and newsroom-illuminating, "News Night" is definitely "back on the air" with Will McAvoy (Jeff Daniels).

"The Newsroom" Season 2 will see several guest stars including Jane Fonda, Patton Oswalt, Marcia Gay Harden and Meryl Streep's daughter Grace Gummer. But according to Chris Messina, who recurs as Reece on Aaron Sorkin's drama, guesting on a series isn't always easy.

"The 'Newsroom' set is very intimidating to me because most of my stuff is with Jane Fonda, Jeff Daniels and Sam Waterston," he told HuffPost TV. "They're all pretty amazing, and being a guest -- and I'm sure even Jane Fonda felt this way -- being a guest on any show, when anyone's in a groove and they feel very comfortable is tough."

"The Newsroom" Season 2 premieres on July 14 at 10 p.m. ET on HBO.
