I watched this film on Sky movies the other night, it is called Saigon here in the UK. It is of course set in Saigon and I think if you took this cop thriller and set it in LA or New York it would just be another average cop film. What makes it different is the setting and the backdrop of the Vietnam conflict. I must admit though I guessed the murderers identity about halfway through the film. It was also refreshing for the guy not to get the girl as it were! A decent if a quite forgotten film.
