Revealing mistake: Except for the one that crashes, every single helicopter in this film is 100% factory fresh, brand new - no mud spatters, no scratched paint, not a dent or a blemish anywhere. They look like they just rolled off the production line. Strange that, on the front line in a war zone and all.
Green Berets (1968)
1 revealing mistake
Directed by: John Wayne, Ray Kellogg
Starring: John Wayne, David Janssen, Jim Hutton, Aldo Ray
Other mistake: After one of Col. Kirby's soldiers has been killed he takes the dead soldier's M-16 and smashes it against a tree. Instead of a magazine the rifle has a plastic sound box, because the 'rifle' is really a toy made by Mattel.
Trivia: Even though the US military had a big part in the production of this film they asked the producer (John Wayne) not to credit them because they thought the movie was so pro-military that it bordered on propaganda.
