Julianne Moore to play Sarah Palin in HBO pic

'Game Change' tells the story of McCain's 2008 presidential run

Julianne Moore as Sarah Palin? You betcha.

The actress has been cast to play the former Alaska governor in HBO’s telepic “Game Change,” an examination of Arizona Sen. John McCain’s failed 2008 presidential campaign. No other casting has been set.

Movie is based on the book of the same name by authors John Heilemann and Mark Halperin. Jay Roach is attached to direct a script from Danny Strong, who previously penned HBO’s Roach-helmed “Recount,” the story behind the 2000 controversial election of George W. Bush over Al Gore.

Roach will exec produce via his Everyman Pictures shingle. No timetable has been announced for when the film will go into production.

Pay cabler has delved into the political arena with its original films on a number of occasions, including “Recount,” which explored the disputed George W. Bush-Al Gore presidential election of 2000, and “The Special Relationship,” which centered on the friendship between President Bill Clinton and British Prime Minister Tony Blair.

Palin, who resigned as governor of Alaska in 2009, has not officially thrown her hat into the ring for the 2012 presidential race, but often appears at Republican Party gatherings. A virtual unknown by both political observers and voters prior to the 2008 Republican convention, Palin was elected by McCain to be his running mate at the GOP’s gathering.

She has been front and center in small-screen iterations before. Mark Burnett-produced “Sarah Palin’s Alaska” ran for nine episodes on TLC and was an initial hit, drawing 5 million viewers in its de- but episode late last year. The show was canceled after the conclusion of its first season.

Moore recently starred in “The Kids Are All Right” and will be seen this summer in Warner Bros.’ “Crazy, Stupid, Love.” On the TV side, she had a recurring role in NBC’s laffer “30 Rock.”

Separately, HBO has acquired rights to the docu “Sing Your Song,” a look at the life of singer-activist Harry Belafonte.

Pic, which will air on the pay cabler in the fall, unspooled at the recent Sundance and Berlin film festivals.

“Song” was directed by Susanne Rostock and produced by Michael Cohl, Gina Belafonte, Jim Brown, William Eigen and Julius R. Nasso.

Deal marks the 11th pic UTA’s Independent Film Group has sold from this year’s Sundance fest.

Belafonte’s lengthy musical career is examined against the backdrop of the civil rights movement, a cause for which he was an active participant. He worked closely with Dr. Martin Luther King for social justice and, later in life, for the struggle against apartheid in South Africa.
