Reading all the other reviews covers all of my impressions - except one - THIS THING kept jumping back and forth between story-lines to the point I wanted to RE-CUT the movie into logical timelines (ADHD?). EACH story was exceptional, and as a pilot, the flying felt like I was in the cockpit (and drowning in a sinking plane!) BUT - almost all the actors had the same dark hair and features, and it took a while to realize I was seeing the same characters in several scenes - NOW, THEN, WHEN? Just confusing, until I caught on.
We watched the NatGEO documentary the night before, and the interesting points mentioned, such as the wharf made out of vehicles, was shown (very understated, but well done...) The discussion of the status of the French in the MOVIE would not have made much sense without watching the NatGeo first.
Mostly, I would say be prepared to watch it TWICE or MORE, so you can absorb the jumps back and forth in the action.
SUPERB acting, especially the yacht skipper, the older pilot, and the Rear Admiral.
THOUSANDS of extras....the Director mostly directed his legions - LOOK UP! DROP to the SAND. JUMP UP! RUN!
This is a story that still rings with the truth of the failure of Leadership, poor logistics, and the determination of Hitler, and what it meant to the world.
Can't wait for the new movie about Winston Churchill....
