Snowpiercer

Snowpiercer, based on the French graphic novel "Le Transperceneige," is set in a future where, after a failed experiment to stop global warming, an Ice Age kills off all life on the planet except for the inhabitants of the Snow Piercer, a train that travels around the globe and is powered by a sacred perpetual-motion engine. A class system evolves on the train but a revolution brews.

I liked this movie a lot.  It was a great take on the overly tried apocalyptic future.  When told the entire movie takes place on a train, you would never imagine that the film would be so creatively cinematography wise but it really was.  The story is excellently told with lots of hooks to characters.  You really feel like you are along for the ride and at no point does the movie drag or get boring.  

I would absolutely recommend people checking this out.  It can be pretty violent at times but it is a great watch and story.   How did this movie get such a small release?
