Watch Julianne Moore as Sarah Palin

Sarah Palin's rise to infamy unfolded for all the world to see, but now we're about to find out what was kept secret from voters in HBO's new TV movie, Game Change.

Based upon a book of the same name, Game Change stars Julianne Moore as Sarah Palin, Ed Harris as John McCain, Woody Harrelson as Steve Schmidt and Justin Gaston (aka Miley Cyrus' underwear model ex as Levi Johnston). The first footage from the film has just gone online and I must admit, Julianne nails Sarah's iconic affectation.

Although I wouldn't expect anything less from the Oscar-winning actress. OK, she's never won an Oscar, which is criminal, but I like to Secret that descriptor into reality by repeatedly writing it.

Game Change will premiere March on HBO.
