Rachel McAdams has confessed that she "got lost" while filming new movie To The Wonder.
The Canadian actress worked with acclaimed director Terrence Malick and Ben Affleck on the movie, which had no set script to stick to.
She told the Telegraph: "Sure, I got lost. Which is an actor's worst nightmare. But it is a gift as well, because great things come out of being lost and unsure, especially if you have a controlling side or a perfectionist side, which plenty of us do."
Rachel added of Tree Of Life filmmaker Malick: "The story just presents itself to him. He puts a lot of clay on the table and sees what comes out of it. Terry himself is so malleable - he keeps things open."
She added: "I was just looking forward to the experience [of working with him] so much. You just trust Terry implicitly. I think he has an amazing eye for great moments and for finding truth and beauty."
