Alison Wright (The Americans) and Benjamin Haigh (The Conjuring 2) have become the latest additions to the cast of TNT’s Snowpiercer pilot, which is based upon the 2013 feature from director Bong Joon Ho and takes place on a frozen, post-apocalyptic Earth where the survivors inhabit a gigantic train that circles the world.

Deadline reports that Wright will portray Lilah Anderson, who is described as “careful and quiet but a pragmatic and independent thinker. Lilah lives with her husband and daughter in a fourth-class cabin and works in the train’s nail salon. Lilah doesn’t know how strong she is, but she’ll soon be forced to find out.”

Haigh is set to play Fergus McConnell, “who lives in the back of the train amongst poverty. He helps his mother care for his sick father, and does his best to contribute to the daily struggles of life in this part of the train.”

Doctor Strange helmer Scott Derrickson is directing the Snowpiercer pilot, which also stars Jennifer Connelly, Daveed Diggs, Mickey Sumner, Annalise Basso and Sasha Frolova.
