Daveed Diggs and Jennifer Connelly star in the new TNT series Snowpiercer. Earlier this month, TNT announced it would be moving up the release of its new science fiction series, Snowpiercer, by a couple of weeks in the wake of the ongoing coronavirus pandemic. And now we have a new full trailer to give us a closer look at what we can expect: essentially a reboot of the critically acclaimed 2013 film by Oscar-winning director Bong Joon-ho (Parasite), fleshed out into a full-length series. Bong's film itself was an adaptation of a 1982 French graphic novel Le Transperceneige, about remnants of humanity trying to survive an ice age inside a 1,001-car train.
