From the press release:
“Titan Comics is thrilled to announce Snowpiercer The Prequel:Part 1:Extinction, a brand-new prequel graphic novel set before the extinction incident that led to the events of the original Snowpiercer graphic novel trilogy. Titan’s next installment in the critically-acclaimed and award-winning Snowpiercer graphic novel saga will be released on September 24, 2019, written by Matz (Triggerman, The Assignment), with art by the original Snowpiercer graphic novel artist Jean-Marc Rochette. Debuting along side Titan’s new graphic novel, the Snowpiercer franchise will also welcome the hotly-anticipated TV adaptation.
Set more than seven years after the world has become a frozen wasteland, the TV adaptation of Snowpiercer centers on the remnants of humanity who inhabit a gigantic, perpetually-moving train that circles the globe. Class warfare, social injustice and the politics of survival are questioned in this riveting television adaptation. The TV series, starring Jennifer Connelly (A Beautiful Mind) and Daveed Diggs (Hamilton, Black-ish), will air in the U.S. on TNT and internationally on Netflix (excluding China)
