After a botched experiment to reverse global warming plunges the planet into another ice age, mankind's few thousand survivors are herded onto the "Snowpiercer," an earth-girdling, self-sustaining bullet train. The rear-car passengers live in crushing destitution, until an uprising is mounted to storm the front-end stronghold of the privileged. Potent parable stars Chris Evans, Ed Harris, Jamie Bell, Octavia Spencer, Tilda Swinton, and John Hurt. 126 min. Widescreen (Enhanced); Soundtrack: English and Korean Dolby Digital 5.1; Subtitles: English (SDH), Spanish; audio commentary; art gallery; featurettes; more.
