A jag from Ice Cold in Alex (1958) via director J. Lee Thompson and Anthony Quayle. Also for Anthony Quinn who has some fun in a minor role as a Greek Cretan who cannot say no to Irene Papas (his co-star in Zorba the Greek (1964), Z (1969)). Carl Foreman (High Noon (1952), The Bridge on the River Kwai (1957)) adapted Alistair MacLean's novel.
Expert mountain-climber Gregory Peck ended up leading a small band of British Army irregulars in an assault on, well, the fictional guns of Navarone during World War II. David Niven went along as an explosives expert, Quinn as an indestructible one-man army, Papas as the daughter of the local rebel who leads them across the Aegean island. James Robertson Justice brought the tonsils to the introductory framing, Allan Cuthbertson some plummy what-ho. Richard Harris has a cameo as an Australian pilot; his accent was middling. Lengthy and things go as they must. Nobody is particularly age appropriate except perhaps the ladies (Papas and Gia Scala).
Bosley Crowther. A band of boring heroic stereotypes. IMDB trivia: the mountain-climbing bit was totally faked. Harrison Ford starred in the sequel Force 10 from Navarone (1978).
