The Green Berets is a 1968 anti-communist propaganda film 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. Unlike most war films, the movie polarized public opinion to this day.
Thematically, The Green Berets is strongly anti-communist and pro-Saigon. It was produced in 1968, at the height of American involvement in the Vietnam War, the same year as the Tet offensive against the largest cities in South Vietnam. John Wayne was prompted by the anti-war atmosphere and social discontent in the U.S. to make this film in countering that. He requested and obtained full military co-operation and materiel from President Johnson.
