Life in Barbie Land Isn't Always Easy Margot Robbie continues to make headlines ahead of the release of the live-action Barbie. This time, director Greta Gerwig spoke with the actress about what goes on behind the scenes during filming.

"The way Barbie operates in Barbie Land, she's completely continuous with her environment," Gerwig explains in a new interview with Rolling Stone magazine. "Because there are no walls in the house, no need to hide. And all of a sudden you find yourself in the real world and you wish you could hide. That's the essence of being human."

Robbie and Ryan Gosling play Barbie and Ken, respectively, in the film. Because of their high profile and the film's buzz, the location became a bit of a spectacle. Gerwig continued, "When Margot and Ryan were actually filming on Venice Beach in their neon rollerblade costumes, it was fascinating because it was actually happening right in front of our eyes.

The director explained that fans treated Robbie differently than his male co-stars. People would walk by Ryan, high-five him, and say, "Wow, Ryan, you look great!" He says. They don't say anything to Margot. They just looked at her. It was surreal. In that moment, I felt she was being self-conscious. As a director, I wanted to protect her. But I also knew that the scene we were shooting had to be one where she felt exposed. And she was exposed, both as a celebrity and as a woman."

"Barbie" opens in theaters July 21.
