Game Change, HBO’s much buzzed-about film based on the 2008 presidential election and the 2010 book of the same name, held its premiere party at Ziegfeld Theatre last night.

Just a few of the celebs FishbowlNY spotted in attendance and on the red carpet: Julianne Moore, who does a spot-on, yet subtle portrayal of Sarah Palin; Sarah Paulson, who plays senior McCain campaign adviser Nicolle Wallace; the film’s executive producer, Tom Hanks, and his wife Rita Wilson; Jeff Zucker; Arianna Huffington; Monster’s Ball producer Lee Daniels; and just about every political pundit in town.

Unlike the book, which focused on all the candidates in the election, the movie zeroes in on John McCain‘s choice (or should we say, his advisers’ decision) to pick Palin as his running mate. And, while many are praising Moore for the way she humanized the Alaskan governor, Ed Harris brought his A-game too. Everything from his mannerisms to his posture were so McCain-like, it was eerie.

Game Change premieres this Saturday, March 10 on HBO. If you don’t mind a spoiler, head over to our sister blog TVNewser for a full review and peep more photos from the event after the jump.
