Global Spy Thriller ’Citadel’ Set to Premiere on Prime Video, Partly Filmed in Morocco

The two episodes of the thriller Citadel will be available on April 28 on Prime Video. A weekly release of one episode per week is also planned. Citadel, which was shot in Morocco, Atlanta, London and Valencia, already has several spin-offs around the world. Its budget is estimated at $240 million, making it the second most expensive series of all time, behind "The Lord of the Rings" whose first season would have cost $465 million.

Game of Thrones actor Richard Madden and acclaimed Indian actress Priyanka Chopra Jonas play the main characters in the series: two high-level spies serving Citadel, an espionage organization that has sworn allegiance to no country.

"Anthony and I have reached a stage in our careers where the ambition of a project is a decisive quality," Joe Russo told Vanity Fair. "We are looking for new ways to tell stories."
