Variety reported in July that a slew of actors had signed on for the first three episodes of the new season.
That cast includes Zazie Beetz ("Atlanta"), Paapa Essiedu ("I May Destroy You"), Josh Hartnett ("The Fear Index"), Aaron Paul ("Breaking Bad"), Kate Mara ("Call Jane"), Danny Ramirez ("Top Gun: Maverick"), Clara Rugaard ("The Rising"), Auden Thornton ("This Is Us"), and Anjana Vasan ("We Are Lady Parts").
According to Variety, it's expected that the cast will expand down the line, with more actors brought on for the season's later episodes.
