The Visitors (1972) Elia Kazan

One of the earliest films about the American involvement in Vietnam is the little known A Yank in Vietnam (1964). The film was directed by and starred Marshall Thompson. It was made in Vietnam before the escalation, the large buildup of American troops, and the anti-war fever back at home. Produced during these early years of the conflict, the film is free of all the political baggage that came only a few years later.  As the American involvement in the war grew and the war became more and more unpopular at home, Hollywood saw Vietnam as a hot potato to be avoided.
