If you’ve seen Westworld, you’d know how brave Thandie Newton is. She’s completely naked in the majority of her scenes as she plays a robot-turned-rebell trying to escape into the world of the living. And it’s epic!

Anyway, the star recently took part in Variety’s “Actors on Actors” series with Oprah Winfrey, and spoke about what it was like.

“It was a moment of such intense self-affirmation, not for me Thandie, but female power,” she said. “I hadn’t felt like that before. And it’s ironic that I was standing there stark naked for a lot of it because I felt more in control than I’ve ever done because I said yes to this.” She later said the show “had secrets for how we need to survive as a humanity, which is to fight for the truth.”

“The showrunner and the director had the crew in such a state of respect and compassion — everyone was so there for me,” she continued. “Every time the camera stopped rolling, he’d say, ‘Stop, stop, stop, let’s get Thandie a robe.’”

The interview will air in its entirety on Variety‘s “Actors on Actors” Season 6, presented by Shutterstock, which premieres June 13 on PBS SoCal.
