<Li> Juney Smith as Sergeant Phil McPherson </Li> <Li> Củ Bà Nguyễn as Jimmy Wah </Li> <P> In 1979, Adrian Cronauer pitched a sitcom based on his experiences as an AFRS DJ . TV networks were not interested, however, because they did not see war as comedy material, even though one of the most popular shows at the time was M * A * S * H. Cronauer then revamped his sitcom into a script for a TV movie of the week, which eventually got the attention of Robin Williams . Very little of Cronauer's original treatment remained after writer Mitch Markowitz was brought in . </P> <P> Commenting on the accuracy of the film, the real - life Cronauer commented "I'm very happy with it . Of course, it was never intended to be an accurate point - by - point biography . It was intended as a piece of entertainment, and (Williams) was playing a character named Adrian Cronauer who shared a lot of my experiences . But actually, he was playing Robin Williams ." Commenting on his portrayal in the film, Cronauer said "Anybody who has been in the military will tell you that if I did half the things in that movie, I'd still be in Leavenworth right now . A lot of Hollywood imagination went into the movie . I was a disk jockey in Vietnam and I did teach English in my spare time . I was not thrown out of Vietnam; I stayed for my full one - year tour and I was honorably discharged ." None of the people in the film are based on actual people Cronauer met, although he described them as stereotypes of military personnel who existed at the time . The scenes where Cronauer teaches his class to swear and use "street slang", his pursuit of a Vietnamese woman, and his Jeep being blown up in the jungle, among others, are constructs for the plot and never happened to Cronauer . </P>
