According to Deadline, Summer will play the role of Bess Till, a brakeman who is part of the train’s security force. In the series, Bess will find herself caught up in a mystery that changes the status quo. “Snowpiercer” is an adaptation of the 2013 film with the same title.

The series is set seven years after the world has turned into a frozen wasteland, and there are only a few people who have survived. They are all living in a train that circles the globe, and each one has a different contribution to their survival. “Snowpiercer” will tackle issues like politics, injustice and class warfare.

Ahead of Summer’s casting, TV Line announced that award-winning actress Jennifer Connelly had been tapped to play the role of Melanie Cavill, a first class passenger working as the voice of the train. Melanie is responsible for making announcements via the train’s PA system. Despite being a member of the upper class, Melanie remains fascinated by those who are different from her, especially those in the lower class.

Meanwhile, Summer’s other film and television credits include a starring role in Noah Baumbach’s film, “Frances Ha.” She is set to star in three upcoming projects, namely, “Battle of the Sexes,” “American Made” and “Caught.” On television, Summer had a recurring role in AMC’s “Low Winter Sun” and Showtime’s “Borgias,” according to TV Line.

“Snowpiercer” is a joint production between Marty Adelstein, Turner’s Studio T and CJ Entertainment. The series is executive produced by Josh Friedman and directed by Scott Derrickson, Tomorrow Studios’ Adelstein and Becky Clements. “Snowpiercer” original producers Bong Joon Ho, Park Chan-wook, Lee Tae-hum and Dooho Choi will all be involved in the upcoming TV series.

As of late, TNT has only ordered a pilot for “Snowpiercer,” and it is unclear if the network will pick it up as an official series. The release date for the series has yet to be announced, but if everything goes as planned, it can premiere in the fall or early next year.
