Bower previously told
If you don't want it spoiled, stop right here. Jamie Campbell Bower was such a convincing villain in his Vecna suit — which took seven hours to put on in the makeup chair — that he actually made Millie Bobby Brown cry real tears of fright while filming one of the scenes in Season 4 of Stranger Things.
Stranger Things Star Millie Bobby Brown Cried the First Time She Saw Vecna. One of the side effects of using practical creature effects?
For Vecna's voice, Henighan says they took Campbell Bower's performance and manipulated his voice so that “the clarity, the strength and the power was there. …
Jamie Campbell Bower's performance as Vecna is so powerful and terrifying that even in real life, on-set, the actor actually made his co-stars afraid of him.
While intending to get his revenge on Eleven and Brenner, Vecna also goes after victims who have dealt with traumatizing experiences in the past (reminiscent of his childhood and his time at the Hawkins lab).
Vecna is also a marvel of special effects wizardry, being mostly practical (giving the actors a physical presence to react to) but decorated with CGI, giving Vecna the appearance of a writhing, repulsive entity, whose tendrils seem to have a mind of their own.
Whenever victims become entranced or possessed by Vecna, their eyes form a milky glaze, until they meet their demise as Vecna plucks their eyeballs out. Also, when Vecna's victims hallucinate — an early indicator they've been targeted by Vecna — the people in their hallucinations have milky eyes.
If Vecna has you in a trance, listening to your favorite song can help pull you out of it, as we saw when Vecna attacked Max only for her friends to pull her out his trance using the synth-tastic stylings of Kate Bush, specifically her 1985 hit “Running Up That Hill (A Deal with God).”
The genius voice actor behind Vecna is Jamie Campbell Bower. Yup, that creepy voice is all him.
However, Bower found Brown's fear of Vecna somewhat amusing and mentioned that he was talking to her inside his mind saying, “No, Jamie's dead. It's just Vecna.” Brown ends it by saying the fear was genuine and that she didn't have to act because she was actually terrified.
Vecna was the original child studied by Dr. Brenner and the son of Victor Creel. He's the infamous Number One, but had his powers blocked and worked as an aide in the Hawkins National Lab.
"Vecna seems to be actually intrigued by Nancy being able to figure him out, to be able to get this close to the truth... I think this is more Vecna's narcissistic traits that pull him to Nancy, why he wants to give her this information."
We know Eleven was born in 1971, which means her mom got pregnant with her during the tests, sometime in 1970. A 1959 flashback in the mid-season 4 finale reveals a 12-year-old One (Jamie Campbell Bower). That puts One, a.k.a. Vecna, as 24 when Eleven was born.
Eleven Was Taught To Access Her Powers Using Lessons Learned From Vecna. Eleven was raised at Hawkins Lab, one of several children granted powers as a result of Dr. Brenner's twisted experiments.
Next up, the viewers go on to theorise that One/Vecna is actually Eleven's dad. Yep, told you it was wild. The theory claims that Brenner wanted to create a child with stronger powers, so he waited until One was old enough to become a father.
(All of which have been cited by show creators the Duffer brothers as inspirations for the villain.) But he does have a surprising weakness: music.
If Vecna can overwhelm their victim with fear, and keep them from resisting, their fate is almost certainly sealed. In the real world, he makes the victim levitate while in their trance, before snapping their bones and neck, and crushing their eyes.
In the finale, Will reveals to Mike that he has retained some kind of link to the Mind Flayer, and that he can "feel" that Vecna is still alive.
Hawkins has suffered a lot of trauma over the years - not all of which is connected to Hawkins Lab and the Upside Down - and Vecna's curse takes advantage of that. Vecna appears to carefully choose people who feel a strong sense of guilt or shame, particularly if those emotions are repressed.
Physically, yes. Lucas tells his friends that Max is in a coma, and we see her wearing casts on her arms and legs. The Duffer brothers have also confirmed that at the end of Season 4, Max is alive yet "brain dead, blind, and all of her bones are broken." The big mystery is where the redhead is mentally.
At his empire's height, Vecna was betrayed and destroyed by his most trusted lieutenant, a vampire called Kas the Bloody-Handed, using a magical sword that Vecna himself had crafted for him, now known as the Sword of Kas.
Jamie Campbell Bower wore a costume and prosthetics to transform into Vecna in "Stranger Things." The actor said that his suit had a "flap" that went over his crotch.
Spoiler alert for Season 4, Vol.
A new featurette video on YouTube showcases how the Stranger Things costuming and effects team were able to transform actor Jamie Campbell Bower into the monstrous Vecna.
However, within the red smoke of Vecna's Mind Lair, it wasn't the song itself that saved her, but the memories it conjured up. What broke through to Max was the happy, loving memories of her friends, particularly Lucas and Eleven, and these were what truly allowed her to break free of Vecna's grasp and escape.
