Harris joins previously announced series lead Chiwetel Ejiofor. The show is based on Walter Tevis’ 1963 novel and the 1976 Nicolas Roeg film that starred David Bowie, both of the same name. In the series version, a new alien character (Ejiofor) arrives on Earth at a turning point in human evolution and must confront his own past to determine our future.

Harris will play Justin Falls, a brilliant scientist and engineer who must conquer her own demons in the race to save two worlds. Production is scheduled to begin in London this spring for a 2022 premiere on Showtime. The show was originally set up at Paramount Plus before moving over to Showtime earlier this month.

“To be working with an actor of Naomie’s caliber is an absolute dream,” said co-showrunners Alex Kurtzman, Jenny Lumet and John Hlavin. “Her strength, her complexity and her bold artistic choices are an inspiration. We couldn’t be more thrilled to have her on board.”

She will next be seen in “Venom 2” and will reprise the role of Eve Moneypenny in the James Bond film “No Time to Die,” her third film in the Bond franchise. Her other feature credits include “Southpaw,” “The Pirates of the Carribean” franchise, “28 Days Later,” and “Rampage.”

She is repped by WME, The Artists Partnership, Untitled Entertainment and The Lede Company.
