Director Joon-ho Bong's Snowpiercer has already opened in several parts of the world, including South Korea, Thailand, Vietnam, Taiwan and Estonia, although it still isn't clear when The Weinstein Company plans on releasing this thriller in North America. Another international trailer has been released, ahead of the graphic novel adaptation's February 7 release in Japan, which features previously unseen footage. Chris Evans, John Hurt, Jamie Bell, Tilda Swinton and Ed Harris star as survivors of a global ice age, who live on a perpetual motion train that circles the globe, where a revolution is brewing against a new class system.
