As I patiently await the release date of the Alita Blu-ray, I was reminded of a fantastic proof-of-concept short film that hit the Web a few years ago. Here below is Henrik Bjerregaard Clausen's super ambitious short, Arene from 2016.
Sadly, it doesn't look like anything more came out of this - though Clausen has since directed two more shorts - but it is definitely cool regardless.
