罗宾．威廉姆斯因主演本片轰动卖座而成为第一线的喜剧巨星。他饰演一名越南美军电台的DJ，每天以妙语如珠的风格主持早晨广播节目，甚受大兵欢迎。后来他深入越南的民间生活，渐渐喜欢上这个国家，以至在节目中发表了一些跟军方宣传有抵触的言论，遭到黯然下台的命运。本片剧本由一位电台主持人根据自己当年在越南的亲身经历撰写而成，故内容特别真实而生动。导演巴里．莱文森以侧面方式来反映越战问题，在同类电影中显得别具新意，此外，穿梭在全片中的多首六十年代流行曲，也可以唤起中年观众的怀旧情绪。 \n \nThe film begins in 1965, when disc jockey Adrian Cronauer (Robin Williams) is assigned to take over the AFR's Saigon radio broadcasts. In contrast to the dull, by-rote announcers that have preceded him, Cronauer is a bundle of dynamite, heralding each broadcast with a loud "Goooooood morning, Vietnaaaaam," playing whatever records tickle his fancy (even those not officially sanctioned by his hidebound superiors), and indulging in wild flights of improvisational fancy. Cronauer's immediate superior Lt. Hauk (Bruno Kirby), whose own notions of humor are puerile and pathetic, jealously attempts to dethrone Vietnam's favorite rock jock. Fortunately, Cronauer's popularity is such that he enjoys the full protection of the higher-ups. But when Cronauer, after experiencing the horrors of war first-hand, insists upon telling his listeners the truth instead of the official government line, he is instantly replaced by the unfunny Hauk and must struggle to get back on the air. \n
