Casting for the "For All Mankind" spin-off called "Star City" has ended

Apple TV+ continues to expand the universe of the show "For All Mankind". While the creators of the original series are preparing a fifth season, its upcoming spin-off "Star City" has finalized its cast.
Joining the previously announced Anna Maxwell Martin ("Good Omens"), Solly McLeod ("House of the Dragon"), Agnes O'Casey ("Black Doves"), and Alice Englert ("Ratched") are joined by Adam Nagaitis ("Chernobyl"), Josef Davies ("Star Wars: Andor"), and Ruby Ashbourne Serkis ("The Letter for the King").
"Star City" will offer a new alternate version of the space race story — this time from the other side of the Iron Curtain. At the center of the story will be the Soviet cosmonauts, engineers, and scouts who risked everything for the conquest of space.
Martin will play Lyudmilla, the head of the KGB surveillance department at Star City. McLeod will play Sasha, a reckless cosmonaut who has yet to live up to his potential. O’Casey will portray Irina, a recent addition to the surveillance department at Star City. Englert will play Anastasia, an untested female cosmonaut in the Soviet Space program. Adam Nagaitis will play the role of Valya, a highly respected cosmonaut within the Soviet Space program. Josef Davies portrays Sergei, a young, brilliant engineer who works at Soviet Ground Control. Ruby Ashbourne Serkis is Tanya, a cosmonaut’s wife that struggles within the confined world of Star City.
