Apocalypse Now is a 1979 American epic war film set during the Vietnam War, directed and produced by Francis Ford Coppola and starring Marlon Brando, Robert Duvall, and Martin Sheen. The film follows the central character, U.S. Army special operations officer Captain Benjamin L. Willard (Sheen), of MACV-SOG, on a mission to kill the renegade and presumed insane U.S. Army Special Forces Colonel Walter E. Kurtz (Brando).
Numerous Hueys appear in the film during the first half, most memorably in the legendary "Ride of Valkyries" beach attack set piece.
These support the Air Cavalry Hueys.
These U.S. Air Force jets drop napalm after Kilgore finishes his attack.
Kilgore communicates with this plane, co-ordinating the napalm bombing.
