Guns of Navarone (1961)

Factual error: Miller rigs his booby trap by attaching the wires from the bomb to a pole down which a metal runner slides, so that when the runner touches the wires it completes the circuit and detonates the bomb. The trouble is, the pole is made of steel, and steel is very conductive indeed. Miller attaches the exposed end of the wire to the pole without any insulation or gap. The circuit will actually be completed when Miller attaches the battery, and he and his booby trap will be blown sky high.

Squadron Leader Howard Barnsby raaf: First, you've got that bloody old fortress on top of that bloody cliff. Then you've got the bloody cliff overhang. You can't even see the bloody cave, let alone the bloody guns. And anyway, we haven't got a bloody bomb big enough to smash that bloody rock. And that's the bloody truth, sir.

Trivia: Peter Grant, future manager of The Yardbirds and Led Zeppelin, had an uncredited bit part in this movie playing a British commando.
