At a historic summit in Spain against global terrorism, the U.S. president (William Hurt) is shot, a bomb explodes, and two federal agents (Dennis Quaid and Matthew Fox) rush to find the culprits. This gripping if ridiculous thriller repeatedly backtracks to present the same events from different viewpoints, though ironically it has no viewpoint of its own, just a desire to pile up plot twists and extend a thrilling car chase ad infinitum. Milking an international crisis for thrills may seem tasteless, but of course the news media do it all the time, which is highlighted by the movie’s shameless lack of interest in such drab matters as political motivation. If you’re up for good nihilist entertainment, look no further. With Forest Whitaker, Sigourney Weaver, Zoe Saldana, and Edgar Ramirez. PG-13, 90 min. (JR)
