Snowpiercer is a 2013 South Korean science fiction action film based on the French graphic novel Le Transperceneige by Jacques Lob, Benjamin Legrand and Jean-Marc Rochette. The film stars Chris Evans, Song Kang-ho, Tilda Swinton, Jamie Bell, Octavia Spencer, John Hurt, and Ed Harris. In 2014, an attempt to counteract global warming through climate engineering catastrophically backfires, resulting in an ice age so severe that nearly all life on Earth is killed. The only survivors are the inhabitants of the Snowpiercer, a massive train powered by a perpetual-motion engine that travels on a globe-spanning track. A class system is installed, with the elites inhabiting the front of the train and the poor inhabiting the tail.
