This film probably would have been better off waiting until this year to see the light of day. Not only is this film more appropriate to a time when the list of people not running for President is almost shorter than the list of people running, but it would have given writer and director Barry Levinson an extra year to decide exactly what film he wanted to make and actually get it right.
There was indeed a disc jockey named Adrian Cronauer who worked for Armed Forces Radio in Saigon during the early years of the Vietnam War. Aside from that fact, this film pretty much deviates from reality from that point forward. If it happens in Good Morning, Vietnam, you be be pretty sure that it didn’t happen to the real Cronauer. This is really the story of what would have happened if you had somehow plunked Robin Williams back in 1965 Vietnam and set him to work for the military radio network.
That’s not to say it’s a bad movie. In fact, it’s the best movie on the pure comic side of William’s filmography, specifically because the role of this DJ perfectly matches the comedian’s unbridled improvisational humor.
