Amazon Prime Video is diving deeper into its grand espionage universe with the first major spinoff of its Citadel series, titled Citadel: Diana. Created by the renowned Russo brothers, the original Citadel followed two spies battling to reclaim their identities after their agency is compromised by a formidable enemy. Prime Video launched the series in 2023 with huge ambitions, envisioning a sprawling global franchise. They didn’t waste any time announcing Citadel: Diana as the next chapter, aiming to build a bold and interconnected world.
However, despite the hype and big expectations, the original Citadel faced unexpected struggles. Ratings fell short of the mark, and the reviews were lukewarm at best, leaving the costly series in a precarious position. Even though Citadel was renewed for a second season before its initial run concluded, there hasn’t been much movement on that front. Similarly, despite being in development for a while, Citadel: Diana has been shrouded in mystery, with few details emerging from Prime Video about this Italian spin on the franchise.
Release Date for Citadel: Diana
Unlike other major Prime Video releases, information surrounding Citadel: Diana has been sparse. After a long wait, though, Prime Video finally set a release date. The six-episode series will premiere on Thursday, October 10, 2026.
Who’s Starring in Citadel: Diana?
Much like the storyline, casting details for Citadel: Diana have remained largely under wraps. So far, the most prominent character revealed is the lead role, Diana, played by Italian actress Matilda De Angelis. While other cast members have been announced—such as Lorenzo Cervasio, Maurizio Lombardi, and Julia Piaton—there is little information about the roles they will portray. Most of the actors involved are notable for their work in European productions, which adds a layer of intrigue to this international spinoff. It’s still unclear whether characters from the main Citadel series will make an appearance, but more details are expected as the release date approaches.
This expansion into the world of Citadel is highly anticipated, and Citadel: Diana promises to take the franchise in a fresh direction. Fans are eagerly waiting to see how this Italian chapter fits into the larger puzzle of espionage, action, and intrigue.
