I found this gem of a short on Vimeo, but you can watch it on YouTube. All I know about this director is he is a filmmaker from Madrid.
The angles and lighting help to convey a tone of pure anxiety. I had to watch it quite a few times as I was completely astonished by this guy’s work. The acting and story line are excellent as well (and there’s a twist at the end), but what stands out for me is the cinematography.
The name of the short is “God Bless You.”
