The Guns of Navarone.

"A British team tries to destroy the guns on Navarone that control the approaches to the eastern Mediterranean Islands." *** "World War II is being fought, and the Germans control the island that guards the approaches to the eastern Mediterranean with big guns. After all other attempts have failed, a five-men British army team is chosen to silence the guns of Navarone. They land on the island, elude the Nazis, and scale a seemingly unclimbable cliff."
