This semi-brainy thriller tries to inject a bit of real world politics into the slam-bang world of The Bourne Identity. Don Cheadle is a conflicted Muslim-American arms dealer stuck in the middle of a massive terrorist plot. Is he on our side, or the side of the extremists? Credit where credit is due, the film creates a realistic, even-handed look inside modern-day terrorism. In the end, though, the crisis of conscience drama and the action thriller fight it out in an uneven battle for supremacy. The thriller loses out, but not before injecting a rather conventional storyline to what could have been a much more psychologically motivated character piece. 114 minutes PG-13.
