Jay Roach will direct a dramatic adaptation of Game Change, John Heilemann and Mark Halperin‘s best-seller about the ’08 election, for HBO. Which means he’ll be casting actors to portray Barack Obama, Hillary Clinton, Bill Clinton, John McCain, Sarah Palin, John Edwards, Elizabeth Edwards and Reille Hunter. Question: If you were Roach would you reach out to Tina Fey to play Palin in a realistic, non-comedic, non-caricature vein, or would you start fresh with someone else?
