MGM+ is doubling down on Stephen King-inspired horror with The Institute, and Season 2 is already shaping up to be even darker, more dangerous, and more unpredictable than before. After a tense first season filled with psychological terror and desperate survival, the series is now moving into a chapter where revenge and exposure could collide in explosive ways.

With production currently underway in Halifax, the upcoming season promises to expand the story beyond escape and into the brutal consequences that follow. And as Luke Ellis and the survivors attempt to stay alive long enough to reveal the truth, the Institute itself may be gaining new allies who are just as frightening as its enemies.

So, as the battle against The Institute escalates, could the survivors be facing an even bigger threat hiding behind wealth and influence?

MGM+ has officially cast Game of Thrones alum Alfie Allen in Season 2 of The Institute, its thriller-horror series based on Stephen King’s novel. According to Deadline, Allen will play Nolan Reeves, described as an eccentric European tech billionaire who is also one of the Institute’s key financial backers.

Reeves is not just a wealthy figure funding the organization from the shadows; he reportedly has an ambitious agenda of his own. That detail alone makes his arrival especially intriguing, since Season 2 will already be dealing with the fallout from the Season 1 finale and the survivors’ efforts to expose the Institute’s crimes while staying one step ahead of ki----- hunting them down.

Meanwhile, Mary-Louise Parker’s ruthless Ms. Sigsby is also set to return, with Season 2 following her pursuit of vengeance and her attempt to regain power while uncovering deeper secrets about the Institute than she ever expected.

Allen joins returning cast members Joe Freeman (Luke Ellis), Ben Barnes (Tim Jamieson), Simone Miller, Fionn Laird, Robert Joy, Arlen So, Jeff Fahey, and Hannah Galway.

With The Institute’s secrets beginning to unravel, could Nolan Reeves be the missing piece that makes the organization even more untouchable?

Alfie Allen is best known for his iconic role as Theon Greyjoy on HBO’s Game of Thrones. This performance earned him Emmy and Tony nominations and made him one of the most recognizable faces from the fantasy juggernaut. His portrayal of Theon’s tragic transformation remains one of the show’s most talked-about character arcs.

Outside Westeros, Allen has continued building a strong career across both film and television. He recently wrapped production on Season 2 of Netflix’s sci-fi epic 3 Body Problem. His recent TV credits also include SAS: Rogue Heroes, along with projects such as Safe Harbour, Atomic, and Girl Taken.

On the film side, Allen has appeared in major titles like Taika Waititi’s Oscar-winning Jojo Rabbit, the John Wick franchise with the exception of the documentary, and The Predator reboot, proving he can shift between gritty action, drama, and high-stakes suspense with ease.

Now, with The Institute, Allen steps into the horror-thriller world as Nolan Reeves, a character positioned to bring even more mystery, power, and danger into an already terrifying story.
