Berthelsen's team is framing this as a bold artistic evolution—a chance for the Danish-Norwegian actress to prove her range beyond the Netflix juggernaut that made her a household name.
Insiders note that Berthelsen has been relatively quiet since Stranger Things wrapped, and this solo play could be her calculated bid to establish herself as a serious stage performer rather than just a one-hit TV wonder.
Berthelsen played Kali Prasad/008 in Stranger Things seasons 2 and the final season on Netflix. Darkling is presented by Actors Touring Company and co-produced with London's Bush Theatre, where she'll make her U.K. stage debut.
This move to solo theater work is either a savvy career pivot or a risky gamble for an actress still best known as the fan-favorite character who could manipulate minds—let's see if audiences buy what she's selling.
Linnea Berthelsen, the Danish-Norwegian actress who captured international attention as Kali Prasad—code name Eight—of Stranger Things infamy, is headed to London's Bush Theatre for her first U.K. stage appearance in a production called Darkling. The solo play marks a significant departure from the Netflix universe that put her on the map, and industry watchers are watching closely to see if this move signals a broader career reinvention. Berthelsen portrayed Kali Prasad in both the second season of Stranger Things and what became the show's final chapter, earning a dedicated fanbase for her character's telekinetic abilities and troubled backstory involving Dr.
Brenner's shadowy experiments. But with that chapter closed and the Duffer Brothers' phenomenon concluded, Berthelsen has been relatively quiet on the acting front—making this theatrical plunge all the more notable. Darkling will be presented by Actors Touring Company in collaboration with the Bush Theatre, a respected institution in London's vibrant theater scene known for championing emerging voices and unconventional storytelling.
A solo play is no small undertaking—it demands complete command of stage presence, emotional endurance, and the kind of raw theatrical chops that don't always translate from screen work. For Berthelsen, this represents either a triumphant expansion of her artistic palette or a calculated gamble in a competitive market where former TV stars often struggle to be taken seriously by theater traditionalists. The production's announcement comes via Variety, which notes this will serve as Berthelsen's U.K. stage debut—a notable milestone for an actress with international recognition but limited theatrical credentials. The timing of this announcement suggests Berthelsen is positioning herself for a post-Stranger Things era where she can define herself on her own terms rather than through association with the show's sprawling ensemble cast and cultural phenomenon status.
