“It certainly is scary. Obviously, people have preconceived ideas about who she was and what she was like,” Natalie told W magazine. “And the first thing you want to be for an audience is believable, of course. So you have to achieve a certain threshold of believability at the beginning just to get people to go to the movie, and to stop seeing you as an actor. So it was scary, but I knew that in the hands of Pablo [Larraín], our director, it was a safe thing to try.”
