The Green Berets is a 1968 American film set in Vietnam, featuring John Wayne, George Takei, David Janssen, Jim Hutton and Aldo Ray, nominally based on the eponymous 1965 book by Robin Moore, though the screenplay has little relation to the book. Thematically, The Green Berets is strongly anti-communist and pro-Saigon. It was produced in 1968, at the height of American involvement in Vietnam, the same year as the Tet offensive against the largest cities in South Vietnam. ... more on Wikipedia
