Yesterday we learned that Linda Cardellini had joined the cast of the upcoming Netflix psychological thriller from the creators of Damages, and now comes news that Sissy Spacek is joining the show as well. Deadline reports that Spacek will play the mother on the show, which stars Cardellini, Kyle Chandler, and a yet-to-be-cast other person as close-knit siblings whose secrets come to light when the black sheep eldest child (Ben Mendelsohn) returns to the fold. Bring it on, Netflix. We are ready.
