After impressing with her guest turn on HBO’s “The Newsroom,” Jane Fonda has committed to her first starring TV series role, a comedy at ABC dubbed “Now What?”

Project came to ABC and ABC Studios as a spec from writer Abby Gewanter (“Pushing Daisies”). Mike Tollin and Ben Spector are exec producing for Tollin Prods.

Scott Ellis (“2 Broke Girls”) is on board to direct and exec produce along with FremantleMedia North America.

The single-camera half-hour revolves around a young woman who publicly criticizes her mother in a blog post entitled “Dear Mom, Here’s Why I Hate You…” Fonda’s character winds up moving in with her daughter, refusing to leave until the two work out their differences.

Fonda’s involvement in “Now What?” marks one of the more high-profile thesp attachments of the 2013 development cycle to date. The two-time Oscar winner earned critical buzz for her role as ruthless media mogul Leona Lansing in four segs of Aaron Sorkin’s “Newsroom.” And she’s likely to generate much pop-culture chatter next year with her portrayal of Nancy Reagan in Lee Daniels’ White House-set drama “The Butler.”

Gewanter’s background in TV ranges from David Milch’s “Deadwood” and “John from Cincinnati” to more recent work on Bryan Fuller’s “Pushing Daisies” and the TBS laffer “Glory Daze.
