In Act I, Scene III of Richard III, Shakespeare wrote that there are places up so high that only eagles got the balls to go up there (exact quote). Schloβ Adler up in the Alps is not one of those places. It’s all Nazis and undercover MI-6 operatives in this joint. No birds at all as far as I noticed.
Loosely based on Disneyland’s Skyway and Matterhorn rides, WHERE EAGLES DARE is the story of a team of British commandos (Richard Burton, others) and one American (Clint) sent on a mission to infiltrate the Nazi-infested castle and rescue a captured general before he’s enhanced-interrogationed into giving up the Allied war plans or something. So they have to skydive, go on a snow trek, mountain climb, sneak in wearing Nazi uniforms, fit in, drink German beer (which Clint was against in THE ROOKIE, saying it has no aftertaste), and all kinds of dangerous shit. (read the rest of this shit…)
