Snowpiecer Comic-Con Trailer Gives Us a First Look at the Long-Delayed TBS Show

Formerly set to air on TNT and currently getting ready to premiere next year on TBS, the long-delayed adaptation of Snowpiercer made its first appearance at San Diego Comic-Con on Saturday afternoon -- revealing a first look at the post-apocalyptic series.

The cast, including Academy Award winner Jennifer Connelly and Hamilton star Daveed Diggs, came with the first footage of the series, which is based on the cult 2013 film of the same name.

The panel kicked off with the first official trailer, which centers on a class war between the affluent people who live at the front of a perpetual motion train that houses the last people on Earth and the "tailies" at the back, who snuck on the train after the world was plunged into an ice age. The tailies were allowed by the train's engineer Mr. Wilford to stay on the train, but only at the back where conditions have a stark contrast to the lavish living of those on the front of the train. Connelly plays Melanie Cavill, the head of hospitality on the train, while Diggs is Andre Layton, the leader of the tailies who kicks off the revolution.

Snowpiercer will officially premiere on TBS "soon" according to the trailer -- although its 2020 release date remains unclear. Getting Snowpiercer on the air has not been without its trials and tribulations, as the show has gone through two showrunners and two directors trying to make it one cohesive series. The series was also originally supposed to air on TNT before moving to TBS earlier this year.

The 2013 movie starred Chris Evans, Ed Harris, Tilda Swinton, Octavia Spencer, and John Hurt, among others. Both the film and show are based on the French graphic novel, Le Transperceneige.
