The actor who plays Vecna in 'Stranger Things' printed out photos of the villain's victims and crossed out their eyes to get in character

• Jamie Campbell Bower says he would print out photos of Vecna's victims to get in character.
• The actor plays the villain on "Stranger Things" and says he had to tap into Vecna's "resentment."

Jamie Campbell Bower, who plays Vecna on season four of "Stranger Things," said he printed out photos of all of the characters victims to "stare at."

Part two of "Stranger Things" season four premiered on Netflix on July 1, bringing the season to a close.

The series, which is one of Netflix's most popular, focuses on the supernatural happenings in the fictional town of Hawkins, Indiana in the 1980s.

Vecna, a villain with psychic powers who has the power to kill people from an alternate dimension, is the newest thread from the Upside Down, a parallel dimension, to menace the town.

Bower told People that in addition to sitting for hours of prosthetic application to get him looking like Vecna, he also did his own work to get into the villain's headspace.

"I would take photographs of each victim," he told the publication. "I'd print them off, my next victim, and I would cross their eyes out and put them up on my wall. And I'd stare at them."

Over the course of the season, Vecna targets teenagers in Hawkins, Indiana who are grappling with their own personal trauma, preying on their fears and eventually killing them.

In addition to printing out photos, Bower said that he would isolate himself and do repetitive exercises to tap into the character's "resentment."

"Preparing was about bringing that up and digging that up more, [which meant] a lot of heavy, dark meditation, low-frequency sounds, a lot of saying the same kind of thing over and over again," Bower told People.

The actor said he would "clear his mind" and repeat certain phrases "over and over and over again" while preparing for the role.

When it came into tapping into Vecna's "fury," Bower said that "music was a big help. I used it to either reignite that or just kind of stay in a zone, and I would sit in sort of pitch black."
