Following on from the news of Julianne Moore being cast as Sarah Palin in HBO’s Game Change, another equally solid actor is now onboard to play her once intended first-in-command.

The Hollywood Reporter has revealed that Ed Harris will play presidential candidate John McCain in the film, which focuses on the Republican’s 2008 presidential campaign and defeat.

The film is being made by Austin Powers/Meet The Parents helmer Jay Roach – a seemingly left-field choice for such material, but he was also behind HBO’s 2008 Emmy-winning politically-themed Recount.
