But if you cant make it out, heres a quick rundown of what audiences saw.

(And Hoyte Van Hoytemas gorgeous cinematography is unmistakable.)

Perspective

The prologue cycles through three points of view during its runtime.

The triptych format shows the full scope of the effort to remove 400,000 Allied troops from the beach.

Between them, they carry a wounded soldier.

Suspense

Even with a short runtime, the segment is wall-to-wall tension.

If there was music during the footage, its difficult to remember.

What will stick in your head is the ever-quickening tick of a clock, placed prominently on the soundtrack.

The sound design is precise and harrowing.

The metallic ka-choong of airplane artillery rattles the theater.

The ticking clock is also built into the story.
