Step aside, Tina Fey, there's a new Sarah Palin impressionist in town! HBO has put out a trailer for its upcoming TV movie, Game Change, about the failed 2008 McCain/Palin tilt at the White House. Julianne Moore is the mama grizzly going rogue; Ed Harris plays presidential running mate John McCain, with Woody Harrelson as his senior strategist, Steve Schmidt. Presumably Moore will be keeping her pants on for this one. Game Change premieres on HBO in the US on 10 March, with UK viewers getting a first look on Sky Atlantic in April. You betcha!
