Alfonso Cuaron’s Apple TV Cult Series ‘Ascension’ Adds Amanda Plummer, Christopher Chung, T’Nia Miller

Alfonso Cuarón’s upcoming Apple TV series “Ascension” has added three new series regulars.

Variety has learned that Amanda Plummer (“Run,” “Butterfly Kiss”), Christopher Chung (“Slow Horses,” “My Brilliant Career”) and T’Nia Miller (“The Haunting of Bly Manor,” “VisionQuest”) have all been cast in the series. Exact character details are being kept under wraps.

As previously reported, Caitríona Balfe will lead the cast, while it was recently announced that Bill Nighy will also star.

The series is inspired by the novel “Last Days” by Adam Nevill. The logline states that it follows Rose (Balfe), “a relentless documentary filmmaker and recently divorced mother, brilliant at uncovering others’ truths but struggling to resolve her own. When Rose begins a project on a mysterious 20th-century cult known as the Church of Ascension, she finds unexpected refuge in its teachings – until she discovers something far more insidious beneath.”

Plummer is repped by Artists Agency in LA, RED Management, and Markham, Froggert, Irwin in London. Chung is repped by The Artists Partnership and Link Entertainment. Miller is repped by Identity Agency and Yorn Levine Barnes.

Alfonso Cuarón is co-writer on the series along with his brother Carlos Cuarón as well as Natalie Erika James (“Apartment 7A,” “Relic”) and Christian White (“Apartment 7A,” “Relic”), with all four executive producing. James and White also serve as co-showrunners, with James serving as lead director. Balfe will executive produce in addition to starring. Alfonso executive produces under his Esperanto Filmoj banner, which has an overall TV deal with Apple.

Esperanto Filmoj’s Gabriela Rodriguez and Richard Schwartz will executive produce. Steve Golin, David Levine and Zack Hayden executive produce for Anonymous Content. Anonymous will produce the show, with Apple Studios serving as the studio.
