She tells Britain's Look magazine, "I don't have to do anything! Hand on heart, I've never been stopped in the street by anyone. Ever. No one recognizes me, which is great. My life hasn't really changed. I don't have to alter anything about my life, really."
And Mulligan reveals she once went completely unrecognized at a film festival in Colorado by a group of people who had just watched her in a movie.
She adds, "I was sitting in a gondola at Telluride Film Festival with six people who had just watched Never Let Me Go. They were having a conversation about it and criticizing it and I was sitting there and they had no idea."
