(Click on a poster to enlarge.)

Plot:
“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.”

Any idea how they get water and food? Do the train stop from time to time to replenish stocks?
