Julianne Moore is going mama grizzly!

The Oscar-nominated actress, 50, has won the role of former Alaska Governor Sarah Palin in HBO's Game Change, according to the Hollywood Reporter.

The film, to be directed by Jay Roach, is based on Mark Halperin and John Heilemann’s book about the 2008 Presidential election.

Politically Moore and Palin, 47,  are on seemingly opposite ends of the spectrum. The Boogie Nights star has actively campaigned for left-leaning causes such as reproductive rights and same-sex marriage, while the former VP candidate is known for her conservative positions.
