In “Dunkirk,” perhaps this year’s earliest Best Picture Contender, a flight of RAF pilots make a crossing to keep the Stukas from strafing “our lads” on the beaches, awaiting their fate. Tom Hardy is in a Spitfire, and Jack Lowden. And the voice, over the radio from the third plane, is the unmistakable Cockney crackle of Michael Caine, sometime Alfred the Butler and decades removed from his RAF days in 1968’s “Battle of Britain. We never see him, or his classic British roadster (Riley, Vincent, Jaguar, Morgan? Alvis!). But he’s there, thanks to Christopher Nolan. You can feel it. That’s texture. That’s a connection to “There’ll always be an England.” #80somethingace.
