Barry Levinson (Wag the Dog)directed this comedy-drama about an Armed Forces Radio disc jockey (Robin Williams) whose manic, hilarious delivery from a studio in 1965 Saigon gives U.S. troops in the field a morale boost (while upsetting military brass). Based on the real-life experiences of deejay Adrian Cronauer, the film is actually more concept than story: put Williams in front of a microphone and let him go nuts. Still, the surrounding stuff about the influence upon Cronauer of the endless deaths among his listeners--as Cronauer tries to stay funny while feeling the mounting losses--is affecting. Williams got a much-deserved Oscar nomination for his work. --Tom Keogh
