The Apple TV series For All Mankind has introduced a spin-off titled Star City, which shifts focus to the Soviet side of its alternate history narrative. This new series features significant recastings, including Agnes O'Casey as Irina Morozova and Alice Englert as Anastasia Belikova, allowing for a fresh exploration of these characters. O'Casey expressed that portraying Irina earlier in her life lets her showcase the character's innocence and development, while Englert noted that the new cast contributes to a distinct atmosphere, making Star City feel like its own entity within the For All Mankind universe. The series also introduces new characters, such as Rhys Ifans and Anna Maxwell Martin, which adds depth to the storyline. The recastings enable a more exploratory narrative, presenting familiar characters at earlier stages in their lives, thereby making the world feel more dynamic and unpredictable. Star City is set to premiere two episodes on May 29, with subsequent episodes released weekly until July 10.
