Julianne Moore has done the impossible. She has matched Tiny Fey’s impersonation of former Alaska Gov. Saran Palin in both looks and mannerisms. She’s featured in a new clip for the upcoming HBO movie “Game Change.”

The movie is based on the non-fiction political book by John Heilemann and Mark Halperin that details Palin’s rise to the vice presidential nomination with Arizona Sen. John McCain.

Ed Harris does a credible job playing McCain and Woody Harrelson plays Steve Schmidt, the senior campaign strategist and advisor to the McCain’s campaign.

Schmidt was the one who apparently suggested that McCain needed a “game changer,” to counter the rise of Barack Obama as the likely Democratic Party nominee and first African-American candidate.

The catalyst for the GOP ticket became Palin, who was elevated from the obscurity of the statehouse in Alaska to a world stage.

At the time, Palin was youngest person and first woman ever to be elected Alaska’s governor. She held the office from Dec. 2006 until she resigned the office in July 2009.

She became a polarizing figure in American politics, but is still embraced by the far right wing of the Republican party, and is said to still be considering a possible run for the GOP 2012 nomination.

The video clip sets the stage for the moving by showing Moore as Palin, making her fateful announcement.

“I will be honored to accept your nomination for vice president of the United States.”

The film will air in March just as the 2012 campaign starts to heat up. Obama is seeking re-election against a broad field of potential Republican candidates.
