What if the world’s most advanced spy network was infiltrated by enemies, and shattered into pieces? This is the thought that sparked the concept for Citadel, Amazon’s first international spy-thriller series that opened the door to an expansive interconnected universe of spies spread across continents. Created by the Russo Brothers, Citadel, is a high-stakes spy-action thriller filled with intense action, unpredictable twists, and a gripping narrative that keeps viewers on the edge of their seats till the very end. Read on to find out how to watch every Citadel TV show in order.
Released in 2023, the series quickly climbed to the top of the streaming charts and received widespread acclaim, prompting Amazon to take the franchise global with a host of non-English spin-offs. In just two years since its release, the Citadel universe has expanded to include regional adaptations, such as Citadel: Honey Bunny and Citadel: Diana, each delivering localised storylines while tying back to the overarching narrative, creating a truly global and interconnected storytelling experience, and becoming a must-watch for fans of action and espionage. But with multiple entry ways to the franchise, deciding how to get started with the Citadel universe can get confusing.
The good news is that each of the Citadel series is designed to stand out on its own. You can dive right into Citadel: Honey Bunny or Citadel: Diana without needing to watch the original Citadel series first. Each show is set in a different part of the world—and sometimes even in a different era—offering unique storylines and local twists. That being said, they’re all happening within the same shared Citadel universe. So, if you’re the kind of viewer who loves connecting the dots, uncovering Easter eggs, and seeing how the bigger picture fits together, we’d recommend watching the series in chronological order to understand the story better.
How to watch every Citadel series in chronological order
Citadel: Honey Bunny
Set in the 1990s, Citadel: Honey Bunny brings viewers back to India for an exhilarating Bollywood style spy-thriller that also serves as the origin story for Citadel’s lead spy, Nadia. This Indian spy-action spin-off follows Honey, an opportunistic stuntman, as he persuades his girlfriend Bunny, an aspiring actress, to join him on a high-stakes covert mission. Together, they are thrust into the murky world of espionage, a journey that changes their lives in ways they never could have imagined.
Citadel Season 1
Citadel Season 1 is the first chapter in the franchise. It sets the stage for the entire Citadel universe. Set right after the fall of Citadel's spy network, the series establishes the stakes for the sprawling narrative and introduces viewers to Manticore, the evil organisation behind the chaos, web of lies, and betrayal that led to the downfall of Citadel.
Citadel: Diana
Set eight years after the fall of Citadel, this Italian spin-off follows Diana, a mole who tries to avenge the death of her parents by working from within the Manticore. The series offers more depth into the world of Manticore, and also delves into the politics of the European spy-network.
