The film "Good Morning, Vietnam" is based on a true story. Set in Saigon in 1965, the film introduces us to Adrian Cronauer (Robin Williams), an Air Force disc jockey who has been airlifted from another assignment to a place at the center of the escalating conflict in Vietnam. The character is based on a real deejay who ran afoul of military authorities in Saigon over the on-air liberties he took regarding issues of style, language and musical taste. In the initial part of the film, it seems that the film will have a comedic style. Cronauner broadcasts his radio station anarchically. He mocked political figures, even the then president, and even the weather. His style and the music he plays have brought laughter and entertainment to the armies, while at the same time antagonizing his immediate supervisors. As the film progresses, the film introduces a Vietnamese girl Trinh who he falls in love with. Try to contact her, she made friends with her brother Tuan and teaches the English class she was in. The film at this point embraces some love comedy factors. Like his unique style as a radio host, he does not teach like others but uses the American style and more often swearing languages. It might seem overly funny, but in the deepest sense, I can't understand the way he portrayed the American people. It's more than just giving them fun lessons on learning the language, but it shows what Cronauner thinks of the American people, which I don't agree with. People around the world curse not only Americans. He simply may have other methods or tactics for teaching the class. There is no way to ask him to teach how good Americans are, but there is also no need to make fun of Americans to gain the approval of others. As Cronauner tries to win Trinh's heart, he befriends her brother Tuan. They often go out together. Cronauner even struggles to get Tuan into a bar usually open only to Americans. The friendship between them saves Cronauner's life twice from bombing the restaurant to saving him from the jungle. While Cronauner later discovered that Tuan was one of the young boys who fought for the opposing side of the American troops, Cronauner felt that he had been betrayed by him.
