The considerable authority of Robert Redford pulls some heavyweight talent into Lions for Lambs, a rare Hollywood foray into flat-out political filmmaking. Three dramas, all connected, play out simultaneously during the same hour: On a mountainside in Afghanistan, two U.S. soldiers (Michael Pena and Derek Luke) find themselves stranded during a new military surge; on Capitol Hill, a Republican senator (Tom Cruise) tries to sell the new strategy to a seasoned reporter (Meryl Streep); and in California, a professor (Redford) tries to light the fire of commitment in an increasingly apathetic college student (Andrew Garfield).
