Her name is Rebecca Van Cleave, and she is 27 years old, and 41-year-old Lena Headey had no issues with a younger woman playing her body double, in part because of the courage it would take for a woman — at any age — to walk through the streets of Dubrovnik while hundreds of people threw things and yelled at her.
“I was like, ‘Listen guys, she happens to have a beautiful body, but I don’t do casting,” Leana Headey said. “If somebody is brave enough to do this, I applaud it.”
For Rebecca Van Cleave — who beat out thousands of others who auditioned for the role — it was actually the first time she ever appeared nude onscreen. She got a lot of help from Heady, though. “Lena was so good about walking beside me and guiding me into what Cersei was thinking and the movements,” Van Cleave told EW.
Van Cleave, a British-American actress, also had her hair cut for the scene.
Here’s her showreel from 2014, which does not yet include Game of Thrones.
