The 27-year-old actress is intimidated by the horrific domestic violence that her character has to undergo in the movie which based on the personal life of Linda Lovelace, reported Contactmusic.
"It was a risky role to play, I suppose, but the nudity didn't scare me. I was more afraid of some of the violence and beatings she suffered, but she was a courageous woman and I've never been so affected by a role as I was by this," Seyfried said.
"The story of Linda Lovelace's life is a very dark place to go. We couldn't show half of what she went through, although our film is still a pretty harrowing experience," she added.
