Jamie Campbell Bower’s portrayal of Vecna has captivated audiences throughout Stranger Things, but Volume 2 of the final season takes his character to even darker territories.
The actor recently opened up about diving deeper into Henry Creel’s tortured psyche, revealing insights that make his villain even more complex than fans realized.
As the series reaches its explosive conclusion, Campbell Bower shares what it’s like inhabiting one of television’s most terrifying antagonists.
And the emotional toll? It’s heavier than anyone might expect.
The Evolution Nobody Saw Coming
When Campbell Bower first signed on for Season 4, he had no idea how deep his character’s story would go. The Duffer Brothers initially kept their cards close to their chest.
I don’t think any of it was pitched to me when I joined. I do remember towards the end of filming the Henry portion of Season 4, Matt and Ross, sort of, we had a little aside conversation, and they were like, ‘This has been amazing. We were always going to bring you back as Vecna, but now we feel like we should bring you back more as you.’
That conversation changed everything. Season 5 Volume 2 reveals crucial backstory about Henry’s transformation, including a devastating childhood memory that explains so much about his psychology.
Viewers witness a young Henry committing murder in a cave—a scene that adds layers to understanding why the monster won’t enter certain spaces in his mind prison.
Playing Monster Versus Playing Human
Campbell Bower distinguishes between three distinct versions of his character: Henry, Mr. Whatsit, and Vecna. Each represents a different stage of humanity’s erosion.
Henry remains closest to innocence and emotional vulnerability. Mr. Whatsit becomes a calculated presentation, burying true intentions beneath performance. Vecna? That’s where love becomes virtually impossible.
I think Henry was so close, was much closer to innocence, was much closer to the experiences, and then when he was sent to that slippery, veiny demise at the end of [Season] 4, it became about resentment, and at that point, it felt like humanity had gone.
The actor describes Henry as having “memory retention, but buried far away.” Uncovering those memories became essential for bringing humanity forward in scenes where he otherwise felt “wildly inhuman, monstrous.”
Working With Young Actors While Playing Evil
One unexpected challenge? Being cruel to child actors while staying in character as Mr. Whatsit—Henry’s deceptive persona.
The Mr. Whatsit side of things, this is a presentation, and the intention is buried. So when you’re sat opposite a child, burying the intention, children, naturally, can see through the BS and lies. It’s a very terrifying experience at times.
Campbell Bower developed particular affection for Jake Bongiovi (who plays a new character) and the younger cast members. Between takes of emotionally intense scenes, they’d play games to lighten the mood.
That table scene in Episode 7—where Henry traps multiple characters in his mind—became unexpectedly joyful despite its dark content.
The Technical Side of Shape-Shifting
Episode 5 features a striking moment where viewers watch Henry transform from One into Vecna in real time. That wasn’t improvised.
Campbell Bower worked extensively with specialists from the video game industry, using techniques called “nodes”—specific physical positions that actors strike and return to during motion capture work.
I was going through my videos the other day, and I’m there on the stage doing it, trying out different things, trying out how I wanted my head to move and where my arms were going to be. Yes, that is a very short moment, but it is something that we spent a long time on.
His background in dance—he studied it through England’s AS Level exams—proved surprisingly useful. Those years of physical training hadn’t disappeared, allowing him to execute the unsettling movements that make Vecna so disturbing.
The Emotional Weight of Darkness
Living inside Vecna’s headspace takes a toll. Campbell Bower has been vocal about finding this character mentally challenging to inhabit for extended periods.
Getting to explore Henry’s traumatic backstory—particularly that cave scene showing his first kill—provided unexpected relief. Those moments of vulnerability felt like “a huge release” after spending so much time in purely monstrous territory.
The actor distinguishes his approach by focusing on resentment as Vecna’s driving force. Once Henry experienced that final betrayal and transformation, the possibility of love became distant—almost impossible.
I refer to love as that thing that keeps us alive, and so I think Henry, if we look at it this way, like Henry is close to innocence, Whatsit is further removed, and Vecna is just like…it’s impossible — virtually impossible — for there to be anything that feels like love.
What’s Coming in the Finale
Volume 2 ends with Holly trapped in Vecna’s clutches as he begins merging dimensions. The two-hour finale promises to deliver answers fans have waited years for.
Campbell Bower teases explosive confrontations ahead, with Episode 8 coming in “steaming hot” directly after Episode 7’s cliffhanger.
After years of playing one of streaming’s most memorable villains, Campbell Bower hopes audiences recognize the humanity beneath the monster. Henry Creel didn’t start as evil—trauma, isolation, and betrayal created Vecna.
That transformation from innocent child to dimension-destroying monster forms the tragic core of Stranger Things‘ final chapters. Understanding how someone loses their capacity for love makes Vecna far more terrifying than any special effect ever could.
