The Hurt Locker, Kathryn Bigelow’s thrilling and hard-hitting war drama, is a master class in sustained tension as a three-strong bomb disposal squad attached to the US Army risks life and severed limb to defuse roadside IEDs. Starring Ralph Fiennes and Anthony Mackie, it’s one of the sharpest and most intelligent films concerning the War in Iraq, but it’s in no way easy viewing.
