It's set seven years after the world has become a frozen wasteland, and the remnants of humanity inhabit a huge, perpetually moving train that circles the globe.
Deadline reports that Connelly will play Melanie Cavill, a first class passenger who spends her days making announcements over the PA system. The character is described as "curiously fascinated" by the lower class passengers, which makes her an oddity among the elite.
Connelly won both an Oscar and a Golden Globe for the 2001 feature "A Beautiful Mind". Though not her first television role, this does mark Connelly's first foray into the medium in nearly two decades.
Connelly only has a few TV entries on her CV with the 1992 (TNT) TV movie The Heart and Justice and the 2000 Darren-Starr-developed series The $treet. That, however, was only a temporary setback for the Snowpiercer. It explores class warfare, social injustice, and the politics of survival. However, as its class divisions remain prevalent, seeds of a revolution are sowed and people like Daveed Diggs's introverted prisoner Layton Well are swept in its force. Doctor Strange director Scott Derrickson is helming the pilot, which has been written by Josh Friedman (Terminator: The Sarah Connor Chronicles), who also serves as showrunner.
The Oscar victor for A Beautiful Mind has been cast as the female lead in TNT's adaptation of feature film Snowpiercer.
