Plenty of movies about WWII focused on a pivotal, successful mission. This 1977 film, based on the Cornelius Ryan bestseller, is about a military operation that went less smoothly. But it’s given the same epic treatment, with a cast to match. Stars include Sean Connery (pictured), Michael Caine, James Caan, Dirk Bogarde, Anthony Hopkins, Laurence Olivier, and Gene Hackman.
