Citadel, starring Priyanka Chopra and Richard Madden, has been streaming on Prime Videos since April 28. The spy thriller also stars Stanley Tucci in a prominent role. The actor, who has various acting credits, including The Transformers, The Hunger Games and Marvel's Captain America, shared his experiences working on Citadel. 

In a conversation with IANS, the actor said, "I think Citadel is probably the largest-scale project I've ever done. I've done big movies, but I've never done a series that has this kind of scope and complexity. And the technology."

"In other words, the technology within the series, but also the technology that's used to make the series," he added. 

Executive produced by the Russo Brothers' AGBO and showrunner David Weil, Citadel also features Lesley Manville in a prominent role. While the first two episodes were released on the first day, each will be released weekly, every Friday through May 26. 

Meanwhile, Citadel has already spawned an Indian adaptation. The Indian adaptation of the series, starring Varun Dhawan and Samantha Ruth Prabhu, will be directed by Raj Nidimoru and Krishna DK.
