We have already reported that Julianne Moore will be starring as Sarah Palin in the upcoming HBO film, based on the best-selling book, Game Change. EW.com, reports that Ed Harris (A History of Violence, Stepmom) has been cast as John McCain.

The film will be a portrayal of the controversial 2008 election. There is no word as to who will be playing Barack Obama or Hilary Clinton but surely they will be well known and possibly Academy Award nominated actors, like Ed Harris.

The film will attempt to truthfully document the politics and publicity surrounding the election. This month HBO’s Mildred Pierce will be released, judging by the quality of the show and its popularity will give a good indication as to what Game Change may be like.
