Snowpiercer

Bong Joon-ho's Snowpiercer is a class-war allegory set on a perpetually moving train carrying humanity's last survivors through a frozen apocalypse. The poor live in squalor at the tail, the rich in opulence at the front, and Chris Evans leads a revolution car by car through increasingly surreal environments. Tilda Swinton's Minister Mason is a grotesque comic creation. The film's structure — each car revealing a new layer of the social hierarchy — is brilliant design.
