“Sounds intense”: Fans buzz as first teaser for ‘The Copenhagen Test’ starring Simu Liu and Melissa Barrera

Peacock debuted the trailer for The Copenhagen Test, a new espionage thriller series starring Simu Liu and Melissa Barrera coming this December 27, 2025. It follows a first-generation Chinese-American intelligence analyst who got his brain hacked. He becomes a puppet to the unseen hackers who now have access to everything that he hears and sees.

The trailer introduces Simu Liu as Alexander Hale, facing danger at every corner, and is caught between his allegiance to his country and doing what his perpetrators want. He meets Michelle (Barrera), whose character is as deceptive as they come in a world where he doesn't know he can trust.

Fans were quick to share their reaction to the trailer, with an X user saying that they will be checking it out because the series sounds intense.

Fans also reveled in the concept of the thriller with someone's brain being hacked, which someone called "wild" and "terrifying." They said that they couldn't wait to see how the story plays out and are excited for the series to premiere on Peacock.

Meanwhile, some fans compared The Copenhagen Test to to British TV series Black Mirror, which features the same themes of AI and the dark consequences of technology. However, one fan said that it's a mashup of Black Mirror and Rami Malek's thriller Mr. Robot, which currently scored a high 94% on Rotten Tomatoes, and they couldn't wait to see it.
