Game Changer is a 2012 English-language Biography Drama movie written by Danny Strong and directed by Jay Roach and produced by Tom Hanks, Gary Goetzman, Jay Roach and Amy Sayers under the banner of HBO Films in collaboration with Playtone. Summer, 2008: John McCain secures the nomination, but polls behind Barack Obama. Strategist Steve Schmidt suggests a game changer: picking a conservative female with media savvy, unknown Alaska governor Sarah Palin, as vice president. She's an immediate hit and a quick study - the gap closes. Then, Tina Fey's impersonation, a raft of criticism, and missing her family send Palin into a near-catatonic state: she doesn't prepare for her Katie Couric interview and bombs. Schmidt searches for an answer: don't expect her to learn the issues, but give her a script. Palin does well in the debate with Biden; she finds her voice, goes off script, and goes rogue. A mistake?
