This has been doing the rounds since April, somehow I missed it. Saw it before a film on the big screen, which was a nice way to be introduced to it.
DP Pat Scola, graded at The Mill by James Bamford. Shot on Tomahawk Beach in New Zealand.
Lots of VFX, according to quotes at themill.com, presumably to keep the weather and time of day looking right because much of it was reportedly shot in the rain.
