One year after Prime Video and the Russo brothers collaborated to bring the ambitious Citadel franchise to life, the first spinoff is ready to premiere. Citadel: Diana. While 2023’s Citadel starred two actors well-known in the U.S. (Priyanka Chopra and Richard Madden), Citadel: Diana branches out to Italy and features well-regarded European performers at the center of its story. It will soon be followed by another spinoff set in India, Citadel: Honey Bunny, which focuses on the past.
