Westworld actress Evan Rachel Wood has said she could no longer stay silent after revealing she has been raped twice.

The 29-year-old, who plays Dolores on Sky Atlantic’s sci-fi Western series, posted an open letter on her Twitter account in which spoke about being attacked by a “significant other” and a bar owner on separate occasions.

She published the letter after giving an interview to Rolling Stone magazine, where she discussed being subjected to “physical, psychological, sexual” abuse and attempting suicide in her early 20s.

Wood wrote: “I don’t believe we live in a time where people can stay silent any longer. I certainly can’t. Not given the state our world is in with its blatant bigotry and sexism.

“It should be talked about because it’s swept under the rug as nothing and I will not accept this as ‘normal’. It’s a serious problem.

“I am still standing. I am alive. I am happy. I am strong. But I am still not ok. Yes, I have been raped. By a significant other while we were together. And on a separate occasion, by the owner of a bar.”

Well, since everything is out in the open now, figured I would share the confession letter I wrote to @RollingStone in its entirety. #NotOk pic.twitter.com/0FSP1gsE36

The American actress, who had previously sent the letter to Rolling Stone, said the attacks happened “many, many years ago” and were “one of the many factors” that contributed to her attempt to take her own life.

Wood, whose life-like robot character on Westworld is shown being dragged off to be raped in the first episode, has previously defended the show’s depiction of sexual violence.

She told Rolling Stone: “The thing about Westworld is we don’t actually show any act of rape.

“I was affected by things being written off as locker-room talk – I had a very, very visceral reaction to it. But the show is definitely a commentary on that.”
