Ed Harris Cast as John McCain in ‘Game Change’ on HBO Opposite Julianne Moore

John McCain should be flattered. Four-time Academy Award nominee Ed Harris has been cast as John McCain in the upcoming HBO film Game Change, though the actor is 14 years the Arizona senator’s junior. Harris will join Julianne Moore, who has been cast as Sarah Palin in the movie based on the John Heilemann and Mark Halperin bestseller about the 2008 election. Game Change will be directed by Jay Roach with a script by Danny Strong.
