It's been several months since we've received any updates about TNT's Snowpiercer television pilot, to be directed by Doctor Strange's Scott Derrickson. However, that changed overnight with a photo from the filmmaker that marks the start of production.

While not particularly revealing, the image shows director's chair emblazoned with the series' logo. Despite the absence of a caption, it's safe to assume this is Derrickson's way of sounding off the train whistle as the series takes to the tracks.

Snowpiercer is a post-apocalyptic allegory for class warfare and the price it takes to keep a capitalist society functioning after an environmental catastrophe results in a new ice age. All that remains of humanity is contained within the various carriages of a perpetually moving train called the Snowpiercer. These carriages form a kind of hierarchy with the worst conditions found at the far end of the train, where inhabitants are kept in squalor and ignorance of the better conditions found in those closer to the engine.

Snowpiercer is based on Le Transperceneige, the 1982 French graphic novel by Jacques Lob and Jean-Marc Rochette, which was adapted in 2013 by Bong Joon-ho as a sci-fi thriller starring Chris Evans and Tilda Swinton. The series will take place seven years after the world has become a frozen wasteland, and like the film, it will provide a platform for an exploration of social injustice, class warfare and the politics of survival.
