Ed Harris just stamped his ticket on the Straight Talk Express.
HBO has announced that Harris, a four time Oscar nominee, will play Senator John McCain in its film adaptation of "Game Change," an insider account of the historic 2008 election, written by Mark Halperin and John Heilemann.
The book follows the campaigns of Arizona Republican McCain and Illinois Democrat Barack Obama in the race for the White House, dispensing inside information and gossip from both camps. The film will be directed by Jay Roach, who won an Emmy for his 2008 HBO film "Recount," about the controversial 2000 Presidential election.
Harris, 60, is 12 years younger than McCain was when he ran for President in 2008.
Harris will be joined in the fictionalized campaign by Julianne Moore, who has already been cast as McCain's running mate, Sarah Palin.
HBO is also producing a miniseries about former Vice President Dick Cheney's career in politics, adopted from the book "Angler: The Cheney Vice Presidency," by Barton Gellman.
