At the same time numerous celebrities in Hollywood were being galvanised into supporting the anti-sexual harassment initiative, Oh was spending much of her time in London filming the first season of BBC thriller Killing Eve.
Despite being separated from the heart of the movement by thousands of miles, Oh felt moved by the tales she heard from women across the globe.
“It was just groundbreaking. I should say even ground-opening. I’m not a survivor, but hearing the flood of stories from women all around the world, it shook me out of my own isolation,” the Golden Globe winner tells InStyle.
“Not only that, it’s also, like, we are not separate. You know what I mean?”
Oh explains how she felt as though she was “living” the ethos of the Time’s Up movement through her work on Killing Eve, as the production team consisted of women supporting one another.
“It was one woman giving another woman a shot,” she says.
“We had [female] characters in their 20s, 30s, 40s, and 50s onscreen and off working together, and I felt f****** great about that.”
While Oh isn’t directly affiliated with the Time’s Up movement, she describes herself as an “absolute ally” of the cause.
During the interview, the Greys Anatomy star also spoke about the insecurities she used to have in her twenties, that have since assuaged with age.
“I was more insecure when I was 20 than I am at 47,” Oh states. “I don’t know what I’m doing. It’s, like, you give less f****.
“Ageing is the greatest,” she adds.
