This interview includes spoilers for the end of season 2 of Snowpiercer
As Ned Stark, the initial if short-lived protagonist of Game of Thrones, Sean Bean was the first actor to utter that showâs signature phrase: âWinter is coming.â In his latest series, Snowpiercer, winter has arrived â the Big Freeze, a cataclysmic temperature collapse that has disabled Earth and forced a few thousand survivors to seek shelter aboard a train that hurtles perpetually around the icy planet. (The premise is taken from a series of graphic novels by Jacque Lob, Jean-Marc Rochette and Benjamin Legrand, as well as from Bong Joon Hoâs film adaptation.) Now, though, the storyâs ice age might be ending; Earth might be warming enough to support life again. Once more, though, the biggest obstacle to this healing is humanity itself.
