I didn’t manage to watch The Challenge in 2017 – it was playing at True/False and in New York while I was there – but I found these shorts by the same filmmaker to tide me over.
Piattaforma Luna (2011 Yuri Ancarani)
Deep-water divers run equipment checks and prepare for a dive, shot mostly in static compositions, though the great opening shot is a slow pull out from a man doing a prayer chant. Are they breathing helium or is something up with the sound recording? Ben Frost provides some lovely rhythmic industrial drone for the start and end segments.
San Siro (2014 Yuri Ancarani)
I liked this one better – workers prepare a soccer stadium for the next game, efficiently moving cables and barriers and doing security sweeps… then some structural views of the team and fans arriving.
