The Guns of Navarone is a 1961 action adventure war film directed by J. Lee Thompson from a screenplay by Carl Foreman, based on Alistair MacLean’s 1957 novel of the same name. Foreman also produced the film. The film stars Gregory Peck, David Niven and Anthony Quinn, along with Stanley Baker, Anthony Quayle, Irene Papas, Gia Scala, Richard Harris and James Darren. The book and the film share a plot: the efforts of an Allied commando unit to destroy a seemingly impregnable German fortress that threatens Allied naval ships in the Aegean Sea.

In 1943, the Axis powers plan an assault on the island of Kheros, where 2,000 British soldiers are marooned, to display their military strength and convince neutral Turkey to join them. 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, the team is composed of Captain Keith Mallory, a renowned spy and an officer with the Long Range Desert Group (LRDG); Colonel Andrea Stavros from the Greek Army; Franklin’s best friend Corporal Miller, an explosives expert and former chemistry professor; Greco-American Spyros Pappadimos, a native of Navarone; and “The Butcher of Barcelona” Brown, an engineer and expert knife fighter.

Disguised as Greek fishermen on a decrepit fishing vessel, they sail across the Aegean Sea, where they successfully overwhelm the crew of a German patrol boat intercepting them. Later in the voyage, Mallory confides to Franklin that Stavros had sworn to kill him after the war because Mallory was inadvertently responsible for the deaths of Stavros’s wife and children. After being shipwrecked on the coast of Navarone during a storm, the experienced mountaineer Mallory leads the team in a climb up the cliff, during which Franklin badly injures his leg. While taking shelter in the mountains, Mallory stops Franklin from killing himself and lies to him that their mission has been scrubbed, and that a major naval attack will be mounted on the coast instead. They rendezvous with two local resistance fighters, Spyros’ sister Maria and her friend Anna, who was once captured and tortured by the Germans before escaping.

German soldiers continually dog the mission. The group is eventually captured in the town of Mandrakos by Oberleutnant Muesel while trying to find a doctor for Franklin (whose leg is infected with gangrene). While being interrogated by SS Hauptsturmführer Sessler, Stavros distracts the Germans and the team overpower their captors. They escape in German uniforms, leaving Franklin behind to receive medical attention. In due course, Franklin is injected with scopolamine and gives up Mallory’s misinformation, as Mallory had hoped. Most forces leave the fortress to counter the expected coastal attack. Upon infiltrating the village of Navarone, however, Miller discovers most of his explosives have been sabotaged and deduces that Anna is the culprit. She confesses that she did not escape but that the Germans recruited her as an informer in exchange for her release. Mallory reluctantly prepares to execute Anna to prevent detection, but Maria intervenes instead and shoots her dead.
