Hollywood’s first movie about the current war in Iraq will include some heavy firepower, in the form of Harrison Ford. Variety reports that Ford will star in an ensemble drama based on the upcoming book No True Glory: The Battle for Fallujah, which is due in May. The manuscript’s author, Bing West, an ex-Marine and former assistant secretary of defense who is now a war correspondent for Slate.com, is writing the screenplay with his son Owen, a Marine rifleman who fought in Iraq. Ford will play Gen. Jim Mattis, who planned the attack on the insurgent stronghold city after four Americans were killed and mutilated there this spring. Mattis’ retaking of Fallujah was just 48 hours away when he was ordered to hold off; the operation didn’t resume until six months later, after the U.S. presidential election. The Marines suffered 28 fatalities during the initial offensive and 50 more six months later.
