Another is Tanya (Octavia Spencer),who is driven to recover a five-year-old son taken by the authorities without reason in what is the latest everyday outrage. The boy,a “train baby” who talks of the “whole wide train” instead of the whole wide world,is seemingly treated as a possession by uncaring rulers who have descended into feudal rule under the command of Mason (Tilda Swinton,aged with make-up and channeling Margaret Thatcher).
Always moving left to right,from one carriage to the next,Bong creates brutal battle scenes marked by striking revolutionary imagery. Like Sergei Eisenstein’sBattleship Potemkin,or Gillo Pontecorvo’sThe Battle of Algiers,Snowpiercer makes the fight for freedom thrilling:when Curtis calls for fire to light a desperate confrontation,the naked flame is carried by differing hands through the carriage in a desperately impassioned relay.
The supporting cast is full of juicy,unexpected roles,most notably a disaffected former security expert,Namgoong Minsu (Song Kang-ho),released from the jail car along with his otherworldly daughter Yona (Go Ah-sung),and tasked with opening doors in exchange for Kronoll,the drug of choice for the upper class. A bored enforcer,Franco the Elder (Vlad Ivanov),never speaks,but his disdain for those he punishes says much about the train’s terrible inequality.
