HBO has, on a fairly regular basis, offered up truly excellent original films, and this one very well may enter the pantheon. Ed Harris stars as John McCain and Julianne Moore as Sarah Palin. Directed by Jay Roach and produced by Tom Hanks, Gary Goetzman, and Roach. The film is going to give us an inside look at John McCain's 2008 presidential campaign, the one where he opted for Sarah Palin as his running mate but failed to gain much traction with the American public. Just where did the whole thing go wrong? Maybe we'll learn tonight.
