Force 10 from Navarone (1978)

Revealing mistake: Near the beginning of the film, when the team are cutting through the wire to steal an aircraft, look closely at the Lancaster bomber in the background. It is obviously a cardboard cutout.

Miller: Don't worry, old chap. Been handling this stuff ever since I blew up the nursery with my first chemistry set. Poor old Nanny.

Trivia: The Chetniks were not one coherent group, as portrayed in the movie. There were in fact two opposing fractions: the first fought alongside the partisans, the others - founded by Kosta Pecanac (the featured group) cooperated with the Germans. Despite their public enmity, though, they still maintained good relations with each other, one of the facts which led to great confusion about the Chetniks among the Allies - probably the reason why they are portrayed here solely as 'bad guys'.
