WATCH: Julianne Moore Plays A Seriously Unhinged Sarah Palin In Game Change

While Tina Fey lent a comic air to her portrayals of Sarah Palin, Julianne Moore is about to play a seriously unhinged version of the rogue vice-presidential candidate in HBO’s Game Change.

That’s not to say Game Change won’t have its funny moments: The movie, which portrays John McCain (played by Ed Harris) as a desperate candidate who made a gamble on the wild-card governor of Alaska, includes Palin’s laughably disastrous interviews with the mainstream media and her hysterical response to the fallout.

“It wasn’t my fault. I wasn’t properly prepped!” Moore/Palin shrieks after the interview where she infamously claimed she could see Russia from her front porch.

But how close to the truth is the film? It’s based on journalists Mark Halperin and John Heilemann’s book of the same name, which was lauded as a reliable account of McCain’s campaign. Of course any movie will dramatize for effect, but we recall Palin denying aides’ requests to prep her for major interviews.

Perhaps she’s just lying after the fact? That wouldn’t exactly be an atypical move for the self-described Mama Grizzly.

Game Change premieres March 10 at 9pm on HBO.
