What if you lost your memory? What if a spy didn’t know they were a spy? Years ago, the top agents of Citadel, Mason Kane (Richard Madden) and Nadia Sinh (Priyanka Chopra Jonas), had their minds wiped.
But, they’re called back to action as sinister forces emerge from the past. With the help of spymaster Bernard Orlick (Stanley Tucci), these former lovers must remember the past to save the future.
Citadel returns to Amazon Prime Video, with the Russo brothers acting as executive producers.
The first season had production budget of US$300 million, the six-episode first season ranks as one of the most expensive television series ever made.
The second season, returned with all seven episodes premiering last month. Around three years after the first season. Which aired week-to-week. Season two arrived with little fanfare, not much marketing and blown out of the water by young adult drama, Off Campus. The show stole all the attention and the chatter. Not to mention it was also another Amazon title.
Citadel was meant to spin-off to multiple non-English language series. Initially these were to be set in, the Italian Alps, India, Spain, and Mexico. The Italian series, Citadel: Diana, premiered on October 2024, while the Indian series, Citadel: Honey Bunny, premiered on November of the same year.
Both of these have now been cancelled, while the Mexico series is off the cards. For now. Season three of Citadel, may also be off the books, with an apparent drop in viewers from seasons one, to two.
