The Snowpiercer show at TNT got another cast member. Mickey Summer, who is probably best known for her role in Frances Ha, will be joining the production according to Deadline. She will be joining already announced cast members Jennifer Connelly and Daveed Diggs in the pilot that will be directed by Scott Derrickson.
Sumner will play Bess Till. Thoughtful, empathetic and savvy, Bess is a brakeman, part of the train's security force. She finds herself at the center of a mystery that rocks the train's uneasy status quo. Connelly plays Melanie Cavill, a First Class passenger who works as the Voice of the Train; Diggs plays Layton Well, a prisoner who becomes a reluctant participant in a struggle that could upend life on the train.
The show is aiming to explore the same social and class stories that the original comic and movie by Bong Joon Ho. There is currently no release date but they are looking at the show premiering in 2018.
