THE COCKLESHELL HEROES (1955)
Maj. Stringer (Jose Ferrer) needs to assemble a crack squad of British Royal Marines for a highly unusual mission. Though Capt. Thompson (Trevor Howard) is extremely skeptical, he dutifully helps his new superior recruit and train the needed men. Their audacious plan involves transporting a small group of soldiers by submarine to the coast of occupied France, where they will kayak along an estuary into a Nazi shipyard and commit sabotage. Chances for success are very small.
