You almost make me want to see it, but shaky-cam in 70mm is a real deal-breaker.

Understood and sympathized. You might have an easier time with Blu-Ray/DVD, although then you lose the immensity and the density of the images, which I did enjoy, especially when the camera held long enough for me to appreciate them. The aerial scenes, in a theater, were great.

I wish E. J. Pratt' 1941 poem 'Dunkirk' was available online so I could point you to it.

I'll look in my local libraries.
