An avalanche is coming toward you. What do you do? That’s theinitial premise of Ruben Östlund’s caustic 2014 black comedy about a family in crisis, but what quickly emerges is a brutal analysis of gender roles and fragile masculinity. Arguably this is the film that launched the modern fascination with cunning Scandinavian cinema, and a conversation about a seemingly self-subverting final act that goes on to this day. – Richard Whittaker
