If you're excited for the new show, we've got a guide on how to watch Citadel that you can use to stream the series, as well as a Citadel episode 1 recap for those of you who've already watched it.

Starring Bodyguard’s Richard Madden and Priyanka Chopra Jonas as special agents Mason Kane and Nadia Sinh, plus Lesley Manville as the villain, The White Lotus star Leo Woodall and Stanley Tucci, Citadel is the Amazon streaming service's effort to make a massive new franchise, as it's been renewed for a second season and local language spin-offs have been announced for Spain, Mexico, India and Italy already.

Amazon Prime has reported: "All of the local series are meant to enhance the entire entertainment experience and will be available for the viewer to deep dive into an imagined layered world.” 

"There are multiple characters and multiple storylines that all intertwine, and I personally play a character who is an amnesiac—eight years of his life, he’s basically become a new person,” Richard explains. “There's a journey of discovering who he was before the accident happened, and he no longer remembers anything. It's a clash between the life that he's been living for eight years, and the life that he used to live. You get to delve into exploring the psyche of dealing with the consequences of things that you're not aware that you've done."

Citadel release date 

Citadel is a six-part series that launched worldwide on Prime Video on Friday, April 28 2023. Its first two episodes were available to stream then, with the rest joining Prime Video weekly.

Is there a trailer for Citadel?

Yes there's a teaser trailer and official trailer released by Prime Video and the action looks intense. Take a look at Richard Madden and the rest in action in both trailers below...

Citadel plot

Citadel is a global spy agency but the six-part story starts by following Laszlo Milla (Roland Møller), the lead operative of Citadel’s rival intelligence agency Manticore after his release from Citadel’s detention facility. He’s seeking revenge on the man who caught him — special agent Mason Kane (Richard Madden) — and wants to bring down Citadel for good. 

The story jumps forward eight years to show that Citadel has been destroyed by an organization called Manticore. One night, when Mason is tracked down by his former Citadel colleague, Bernard Orlick (Stanley Tucci), who desperately needs his help to prevent Manticore from establishing a new world order. Mason seeks out his former partner, Nadia Sinh (Priyanka Chopra Jonas) — they'd both had their memories wiped and have been living separate lives. Now the two spies embark on a mission that takes them around the world in an effort to stop Manticore, all while contending with a relationship built on secrets, lies, and a dangerous-yet-undying love.

Citadel cast — Richard Madden on playing special agent Mason Kane

Richard Madden plays Mason Kane, a special agent who works for Citadel intelligence agency. 

"The joy of this is being able to play these two very different characters, but both in the same body," explains Richard. "And they are both the same man in lots of different ways, but in each version of them, you pull out different aspects of humanity and who we are as people. And one of them carries a lot of scars from the past and a lot of trauma. And the other one doesn’t carry any of that baggage. He just has a whole bunch of unknowns to him, so we end up having these two very different characters. And that’s kind of what was exciting to explore about them, is how much of your character traits are built into you, and how much is inherited through trauma and experience?

" Ithink oftentimes, we see shows that are 80% drama, 20% action, or vice versa. And this show aimed to be 100% of both. And I think that’s what we’ve managed to pull off, ‘cause, in the middle of these huge sequences with explosions and cars blowing up and all of that, I don’t want to spoil it for you, we have this really kind of intimate drama between these two characters and how they dance together. So, for me, that's what was so exciting about these huge action pieces was that they were infused with heart and drama, and storytelling. We get to see a lot about these characters and how they physically interact. Not just great action sequences, but there's drama at the heart of each one of them."

* After playing Robb Stark in Game of Thrones and Prince Kit in Cinderella, Richard Madden hit the big time in the BBC1 thriller Bodyguard, which also starred Keeley Hawes. He’s also appeared in Birdsong, Lady Chatterley’s Lover, The Take, Rocketman, 1917 and Eternals

Priyanka Chopra Jonas on playing Citadel agent Nadia Sinh

Indian singer and actress Priyanka Chopra Jonas is Citadel agent Nadia Sinh. 

Priyanka says: "Citadel is a secret spy organization that has been created by the governments of the world. After multiple wars and conflicts erupted around the world, where governments decided that they were going to share intelligence and that it's for the betterment of the world to be able to share intelligence rather than keep intelligence because of all kinds of terrorism and, you know, a conflict that arose. So it's for the good of the world. It's for the good of humanity. And it needed to be kept a secret from the general public because it was to protect them and to protect the identities of thousands of Citadel spies all over the world. So it's a really unique, interesting concept. 

"Our characters have sides to them and their personalities. Nadia carries a lot of baggage. She has to navigate really thick waters, you know? She has to hold her head up high while her character’s changing, her life is changing all around her, but she has to stay centered because of the burdens that she carries. I think that that makes her very juicy as a character for me to play because every choice that is made by her is burdened and laden by so much pressure. And she thrives in it, so it was really wonderful."

* Priyanka Chopra Jonas previously played Pinky in The White Tiger. She’s also starred in Baywatch, Isn’t it Romantic?, Quantico, We Can Be Heroes and The Matrix Resurrections

Stanley Tucci on playing Bernard Orlick

Stanley Tucci plays Bernard Orlick  a former Citadel colleague who recruits the spies for a mission to stop Manticore.

"I liked Citadel because it was complicated. There was something very captivating and unusual. I liked the character because there was humor to him, but there was also a real depth to him, and you never knew where it was going to go. I didn’t want to do that thing where he’s just the nerdy guy, and it wasn’t written like that either. He’s slightly more deadly. He has experience in the field as well as calling the shots from the office or a remote location. So I thought that was really interesting because usually, there’s the guy that’s in the field, and then there’s the tech guy, and there’s the boss guy, and this was all kind of a jumble, and I like that."

Anthony Russo adds: "Stanley Tucci is just such a wonderful, inventive, playful, intelligent actor that he really pushes their buttons in fun ways, and he makes the most of the dramatic relationship these characters have."

* American star Stanley Tucci already has a number of hit movies and TV series under his belt, including two seasons of Stanley Tucci: Searching for Italy, The Hunger Games, The Lovely Bones, Captain America: The First Avenger, Julie & Julia, Big Night, Spotlight, Inside Man and The Witches. He’s also starred in The Devil Wears Prada, The Terminal, The Pelican Brief and Prizzi’s Honor.

Lesley Manville on playing Dahlia Archer

The villain of the series is Dahlia Archer, a powerful woman employed by some dark forces who stops at nothing to get what she wants. She's played by Lesley Manville who says: "I was very interested in Citadel because the project sounded very exciting. It’s a big epic thriller with so many elements to it. It’s a series I’ve not made a lot of in terms of style, so that was something new to me. And the character of Dahlia was just too good to resist. She’s the UK Ambassador to the United States, with this really dark side and facade of someone reliable and honorable. But she’s far from honorable, she’s self-serving, she’s manipulative, she’s really quite the bad person, and I thought this is going to be great to play. 

"It’s not which is easiest or which is hardest. Every part I play is different, and that’s the kind of actress I am and will continue to be. I’m not an actress who only has one type of performance in her. I like to play different ends of the social scale, and I like to play characters that are really not like me and very different from each other. But there’s no harder or easier. They’re all a challenge. It’s as complicated to create a sweet and wholesome character like Mrs. Harris as it is to create a thoroughly evil character like Dahlia."

* Lesley Manville plays Princess Margaret in The Crown season 5 and has starred in dramas such as Magpie Murders and the movie Mrs Harris Goes to Paris.
