The `Mirror Mirror` star made her Broadway debut in `Three Days of Rain` in 2006 and although she has plans to return to the theatre, the actress - who has three children, twins Hazel and Phinnaeus, seven and Henry, four, with husband Danny Moder - admitted it wasn`t the easiest experience ever.

She said: "It`s like childbirth, you don`t know until you`ve done it but you get a little bit away from it and you go, `Of course I want to do that again`. You get sucked back into doing theatre because it`s really thrilling and does challenge you as an actor in really unique ways. You know, I love the medium of film, I love that environment but it`s just different."

Julia also believes she would enjoy the experience more this time around.

She told the new issue of Vanity Fair magazine: "I really enjoyed doing `Three Days of Rain` but I could definitely find ways to have more fun because now I have a much better sense of what I`m getting into. I mean when we did `Three Days of Rain`, I had two little children and was doing eight shows a week. There was a relentlessness to it that you can`t understand if you haven`t been in that situation."
