If you have it, spend it: Italian artist Yuri Ancarani’s visually striking documentary enters the surreal world of wealthy Qatari sheikhs who moonlight as amateur falconers, with no expenses spared along the way. The Challenge follows these men through the rituals that define their lives: perilously racing blacked-out SUVs up and down sand dunes; sharing communal meals; taking their Ferraris out for a spin with their pet cheetahs riding shotgun; and much more. Ancarani’s film is a sly meditation on the collective pursuit of idiosyncratic desires. A 2017 New Directors/New Films selection. A Kino Lorber release.
