The Citadel spy universe from Amazon MGM Studios all began with Citadel in 2023, kicking off an expensive multi-series global storytelling event. Even with mixed reviews, the studio invested in creator David Weils vision to tell connected stories about a spy agency in ruins. The first spinoff was Citadel: Diana the second is Citadel: Honey Bunny. The former detailed undercover agent Diana Vavalieris journey out of enemy lines in Italy with the help of the heir of Citadels villainous competitor, Manticore. Met with better reviews than Citadel, it seemed the spinoffs could be the positive reel we needed.
