A quote from an experienced moviegoer:
Has anyone seen it in 70mm imax and regular 70mm? Is it worth it to see it in the non imax 70mm version?
Yes, I saw both. The standard 70mm is definitely a different experience from the 15/70 film, but it's still a wonderful and authentic way to view the film. If I'm brutally honest, of course 15/70 is the way to experience the film (and you don't just watch it in 15/70, you experience it), but the standard 70mm print I saw on opening weekend was gorgeous, just like the print of The Hateful Eight I saw at the same theater.
If you can't get to a 15/70 show (and remember, most can't without a trek), then I would, by all means, see it in standard 70mm instead. Apparently, there are also a handful of theaters showing the film via 35mm reduction prints, but those are few and probably far between. I haven't seen IMAX Laser, so I can't comment, but that would be my next choice, as even though it is digital, you get most/all the picture information from the IMAX 15/70 version. Otherwise, if you must go digital, I guess try and make sure they are running the 4K DCP in native 4K, and not on a 2K system.
In short, if it's possible for you to see it on film, do so, and see it on the biggest film, and the biggest screen you can.

As for Conrad Black's article on Dunkirk, global warming and the heat wave starting tomorrow on the Northern West coast: He can write all the books and articles he wants about history and the state-of-the-affairs in North America and abroad. He can even tweet, and write in any newspapers any news that we already knew way ahead of him.
Thank you very much; Dunkirk in the year 1940 (seventy-seven years ago) we get the best information sources from the best in the history business.
I will see the film, and starting tomorrow stay in the shade with light color clothes and a large cold water bottle. That's for the North West coast...heat wave.
And it has nothing to do with Dunkirk or/and global warming. :b It's just a Pacific weather pattern thing.
