Amazon is not proceeding with the Citadel international offshoots Citadel: Honey Bunny and Citadel: Diana, which will not be returning for second seasons. Meanwhile, the upcoming second season of the mothership series starring Richard Madden and Priyanka Chopra-Jonas has gotten a Season 2 premiere window and an official logline.

“Having successfully traversed India and Italy, storylines from both Citadel: Honey Bunny and Citadel: Diana will be woven into the upcoming second season of the mothership series Citadel,” Vernon Sanders, head of television, Amazon MGM Studios, said. “While these successful and widely enjoyed international chapters will not continue as individual series, Season 2 of Citadel will be our most exhilarating yet. With high-stakes storytelling, new additions to our amazing cast and bold, cinematic ambition, the new season will deepen the emotional journeys of Nadia, Mason, and Orlick against the relentless force that is Manticore. We’re excited to share what’s next when Citadel Season 2 premieres globally in Q2 of 2026.”

The cancellation of the two spinoff series is not surprising. While they have done well in their local markets, Citadel: Diana and Citadel: Honey Bunny have not been global breakouts and have been waiting for word on their fates since launching their first seasons in September and December, respectively.

Additionally, as Deadline reported last month, plans for other potential spinoffs in countries like Mexico have been put on hold as the focus is put squarely on finishing Season 2 of the main series.

The Citadel franchise has been under scrutiny following the recent exit of Amazon MGM Studios head Jennifer Salke on whose idea it was based. It was probably the biggest gamble of her tenure — an ambitious, expansive and expensive multi-series, multi-country endeavor for which she brought in the Russo brothers‘ AGBO.

Season 2 of the mothership series is currently in post-production. It was targeting a late 2025 delivery and previously eying a Q1 2026 release. It will now debut about three years after the April 28, 2023 Season 1 premiere.

Season 2 is set one month after the events of the first season. In it, we find our Citadel spies underground, as they’re being hunted by Manticore agents around the world. They’re pulled out of hiding to join forces with a new team of unconventional spies when Manticore’s Brazilian billionaire Paulo Braga threatens to unleash a cataclysmic piece of technology, built by Citadel’s own Bernard Orlick, into the world.

The series made headlines with its tortured development and Season 1 production history that included multiple showrunner changes, multiple cuts and reshoots that reportedly pushed the budget north of $200 million for six episodes. It delivered respectable but not extraordinary ratings performance — Citadel became at the time Prime Video’s second-most-watched new original series outside the U.S. and fourth-most-watched worldwide after 24 days of release with modest U.S. viewership..

From Amazon MGM Studios and AGBO, Citadel is executive produced by Anthony Russo, Joe Russo, Angela Russo-Otstot and Scott Nemes for AGBO, with David Weil serving as showrunner and executive producer.
