 Rescue by the Royal Navy is prevented by two massive radar-directed large-calibre guns on (fictional) nearby Navarone Island.When aerial bombing efforts fail, Allied Intelligence gathers a commando unit to infiltrate Navarone and destroy the guns.Led by Major Roy Franklin (Anthony Quayle), the team is composed of Captain Keith Mallory (Gregory Peck), a renowned spy and an officer with the Long Range Desert Group (LRDG); Colonel Andrea Stavrou (Anthony Quinn) from the defeated Greek Army; Franklin's best friend Corporal Miller (David Niven), an explosives expert and former chemistry teacher; Greco-American Spyros Pappadimos (James Darren), a native of Navarone; and "Butcher" Brown (Stanley Baker), an engineer and expert knife fighter.
