Kathryn Bigelow’s heart-stopping Iraq war drama (2009) follows a U.S. army bomb squad around Baghdad as it defuses IEDs, a job that places the men in potentially deadly situations a dozen times a day. After the squad’s explosives expert is killed in action, he’s replaced by a shameless cowboy (Jeremy Renner) whose needless risk-taking infuriates his two partners (Anthony Mackie, Brian Geraghty). He’s a true warrior, but Bigelow defines that in terms of addiction; as one of the other soldiers points out, he doesn’t mind endangering them to get his daily “adrenaline fix.” The war has already produced some excellent fiction films (The Lucky Ones, In the Valley of Elah), but this is the first to dispense with the controversy surrounding the invasion and focus on the timeless subject of men in combat. It’s the best war movie since Full Metal Jacket. With Ralph Fiennes and David Morse. R, 130 min.
