John Wayne wins the Vietnam War in a movie that bears zero resemblance to the actual conflict – not least because it was shot in Georgia. It’s based on a bestseller by special forces veteran Robin Moore (who also wrote the book on which The French Connection is based), but US Army cooperation was contingent on Moore being jettisoned from the production and he was paid out. That might explain why this lionising version of events, in which Wayne’s upstanding Colonel Kirby tackles the villainous commies and cuddles some orphans, works better as a study of wartime propaganda than a movie.
The expert view: ‘Even watching in a black-and-white TV as a kid, The Green Berets seemed propagandistic – and that's exactly what it was. It was designed to build support for the war on behalf of this brave little democratic regime fighting against the Red Menace. Almost anything with John Wayne is bound not to be accurate.’
