She was just 8 when she filmed the hit series. Darby told New York Magazine of her career aspirations, "I want to be an actor when I get older. Yes, I do. I think Reese [Witherspoon] said, 'Don't do the main character in big TV shows, like every single episode, every single season. Don't be started on that.' She started on movies and drama and that kind of stuff. She said that's how she started out, and that would be better for a child." Darby also appeared on "Grey's Anatomy" in 2017.
