EXCLUSIVE: Foundation star Sandra Yi Sencindiver has joined FX and Noah Hawley’s Alien series which is filming in Thailand.
Exec-produced by Ridley Scott, the prequel series will be set towards the end of this century (a few years before Prometheus, and some thirty years before Scott’s film). It’ll be the first project in the franchise to take place on Earth and has been reported to deal with the emergence of the story’s infamous Weyland-Yutani Corporation and the race between corporations to create new android life.
The series will star Sydney Chandler, Alex Lawther, Essie Davis, Adarsh Gourav, Kit Young, Timothy Olyphant, David Rysdahl, Babou Cessay, Erana James, Lily Newmark and Adrian Edmonson.
