Snowpiercer is a television series based on the movie of the same name, starring Jennifer Connelly, Daveed Diggs, and an expanding cast of characters who, mostly, represent the less-than-respectable aspects of humanity.
The Snowpiercer itself is a train, 1000 cars long, that houses the last remaining humans on Earth. With the planet frozen over, one man's vision was to create a train that would keep traveling around the globe, generating heat and being a self-sustaining environment to support everyone until... well, until the world warmed up again, I suppose. As plans go, I'd have probably opted for a space station, or an underground bunker. But, hey, who doesn't love a train? And maybe we'll even get a toy line out of it.
