Bong Joon-ho's 'Snowpiercer' is opening (at least internationally) right before Neill Blomkamp's 'Elysium,' and it's interesting that two world-class filmmakers are using science-fiction to address the inequalities in the world. The "Occupy Wall Street" movement obviously sparked a lot of imaginations.

In this latest trailer, the plot becomes obvious: There are survivors on a train that's run by Tilda Swinton (who seems to be doing a riff on Margaret Thatcher). The lower class are treated poorly so it's up to Chris Evans and his band of outsiders to take the train over. The film has a great international cast, which includes Joon-ho regular Song Kang-ho alongside such familiar faces as Alison Pill, John Hurt, Ed Harris, Jamie Bell, and Octavia Spencer.

Currently the film doesn't have a release date stateside, but The Weinstein Company are set to distribute it, and with the film opening in international markets August 1, it's likely they'll try to get it into theaters this fall. After 'Memories of Murder,' 'The Host' and 'Mother,' it's apparent that Bong Joon-ho is one of the greatest working directors and we can't wait to see what he does with this material, which is based on the French comic 'Le Transperceneige'.

The Film Stage also found these making-of spots, though they're mostly in Korean. They do feature interviews with much of the main cast.
