Elisabeth Moss, the powerhouse star and co-producer of Hulu’s hit adaptation of “The Handmaid’s Tale,” has no small list of challenges in portraying Offred, a woman conscripted as a reproductive slave in a dystopian theocracy called Gilead.

Not least: Filming scenes in which her character is routinely, clinically raped by her commander (Joseph Fiennes) in order to conceive a child. In a roundtable discussion for The Hollywood Reporter, Moss opened up about her process and the undeniable horror of her character’s victimization.

Speaking with five other actresses, including Oprah Winfrey and Nicole Kidman, she elaborated on previous thoughts she’s offered about depicting Offred’s rape on screen. “It was really important for us to have it be extremely clinical, mechanical; there’s nothing remotely sexual about it,” she said.

Moss also explained how she prepared to portray her character during these harrowing scenes:

I just thought, “What would one do in this situation?” Which sounds so oversimple, perhaps, but I was just like, “If you were being sexually assaulted on a regular basis and you knew there was nothing you could do about it, what would you do?” There’s no escape and you can’t fight back. And so I thought, “Well, she would probably try not to be there — try to go somewhere else.”

The trauma Offred suffered would have been so extreme, Moss suggested during the THR roundtable, that allowing herself to experience it would be impossible. “You can’t experience it,” she said. “You wouldn’t make it. Which happens to women in that world; they don’t make it.”
