Nine international character posters have been released for Snowpiercer, the English-language debut of Korean director Bong Joon-ho (The Host).  The story is set in a new ice age caused by a failed experiment to stop global warming that killed virtually all life on the planet.  The sole survivors live on a train called Snowpiercer—powered by a perpetual machine—who struggle with the class system implemented on the train.  The posters all provide the first hint of a release date by listing "Summer 2013".  However, since these are international posters, we don't know if that's summer for the U.S., other countries, or both.

Hit the jump to check out the posters.  The film stars Chris Evans, John Hurt, Tilda Swinton, Jamie Bell, Ed Harris, Ewen Bremner, Octavia Spencer, Kang-ho Song, and Ko Asung.
