That means that when you're in the cockpit of a fighter diving towards the water, or running behind an infantryman dodging German snipers, the idea of 'tunnel vision,' a phrase spoken by many a catastrophe survivor, comes to life onscreen. It's close to the old-fashioned 'Academy' ratio common to films made in cinema's early decades: squarish, tall instead of wide. And if you see the movie in one of the handful of theaters showing it in 70mm IMAX format, the experience will feel even more constricting and oppressive because of the image's unusual shape.

Fear of heights, fire, drowning, confined spaces, darkness, abandonment-you name it, it's represented in cinematographer Hoyte van Hoytema's nightmarishly clear images. If you were to make a list of every phobia you can think of, you'd have to tick off a lot of boxes after seeing this film.
