Amber Heard has "lost [her] ability to speak" in the wake of her legal battle with Johnny Depp

In a confessional interview for Silenced - which has premiered at the Sundance Film Festival - with director Selina Miles, Amber said: "This is not about me. I have lost my ability to speak. I am not here to tell my story. I don't want to tell my story. In fact, I don't want to use my voice anymore. That's the problem."

International human rights lawyer Jennifer Robinson is also involved with the documentary, and she assisted Amber with her participation in Johnny's 2018 libel lawsuit against The Sun newspaper, after they branded him a "wife-beater", and she recalled how her former spouse's fans shouted and jeered at her as she made her way to and from court.

She said: "The outcome of that trial depended on my participation, and I depended on the outcome of that trial. When I first met [Robinson], I immediately got the sense that she got the bigger picture. What has happened to me is an amplified version of what a lot of women live through.

"I remember at the close of the trial, the idea that I could say something to the press came up. [Robinson] asked if I was sure about that. [I thought], 'If they throw things at me, it will make this point more obvious.' I didn't understand it could get so much worse for me as a woman, using my voice."

But the 39-year-old star has been given hope by seeing women speaking out.

She said: "It gives me strength seeing other people take on the fight. Women brave enough to address the imbalance of power. Looking at my daughter's face as she grows up and slowly starts to walk into this world... I believe it can be better."

While Johnny lost his libel claim against The Sun, he also sued Amber for defamation for an op-ed she penned about surviving domestic abuse - although she did not name him in the piece - and the jury sided with the Black Mass actor, awarding him $1 million in damages.
