The Copenhagen Test explores a near-future world where intelligence agencies, surveillance technology and personal identity collide. The series was created, written and showrun by Thomas Brandon, with Jennifer Yale serving as co-showrunner and executive producer.
Led by Simu Liu, who stars in the series and also serves as an executive producer, The Copenhagen Test centers on an intelligence analyst whose reality begins to unravel as powerful forces gain access to his mind. The show examines themes of surveillance, trust and human connection in a world where privacy is increasingly fragile.
“I think on the one hand, it was definitely the premise and the world building, just dealing with themes of surveillance and technology,” Liu told Deadline about what drew him to the role. “I feel like a lot of those things are really just topical and relevant today. And so, I think there was that. I really appreciated Thomas’ take on this 5 minutes into the future, set in this world of intelligence.”
The series, now streaming on Peacock, also stars Melissa Barrera, along with several familiar faces.
