The actor, who played Stephen King's killer clown, told Entertainment Weekly playing Pennywise for so long affected his attitude in many ways.

“It’s just like being in a very destructive relationship,” Skarsgård said. “After we wrapped, I was in my childhood home in Sweden, sitting having coffee with my mom at our kitchen table, and realized, ‘Oh, holy sh—, I don’t have to deal with this relationship anymore!’ It was a very quick shift of just feeling better.”

“I likened it to an exorcism—him exiting my body and getting rid of the Pennywise toxins,” the actor continued.

However, getting rid of the character wasn't easy..

“I was home, done with the movie, and I started having very strange and vivid Pennywise dreams. Every night, he came and visited,” Skarsgård explained the clown took on different forms during these nightmares. “It was in the shape of either me dealing with him, sort of Pennywise as a separate entity of me, and then also me as Pennywise in circumstances that I didn’t appreciate. Like, I’m Pennywise and I’m really upset that I’m out in public and people are looking at me.”

“This was a process of letting go of the monster,” he declared.
