Roberts and the fact that a project needs to be outsanding before she signs on:

"It does. It’s a hard decision to make. People talk about the balance and all this sort of stuff, and it really is, it’s funny because you want to sort of work and have it not be a decision to not be with your family. And I’m lucky enough to be in a job where my kids can come to work with me and all that kind of stuff, so it makes it a little easier to make those kinds of decisions to go off. And I have a movie that I’m going to do next year, so I’m looking forward to that and it’s nice to kind of have that ahead and know that that’s there."

On the next project she's signed on for:

"It’s no secret. It’s a movie that I’m doing with Clive Owen called Duplicity."

On how she'll explain her celebrity status to her kids:

"I am treated pretty normally. I realize more and more that life is about energy, and the energy that I put out is very much a lot of the energy that I get back, or the energy that’s given to me becomes very much sort of then how I conduct myself. We live a pretty quiet normal life. I have two 3-year-olds that are very aware, open people, and they’ve never experienced anything out with me in the world where they’ve said, 'What’s that about?' So I think that is an accomplishment and a testament to the quietness of our life, that nothing has ever happened where they are like, ‘What the hell is going on?'"

Roberts on whether she's more aware of the environment after becoming a mother:

"Absolutely, one-thousand percent. They [her children] are perfect, and you think, ‘How can I help sustain their state of bliss and progress?’ And really beating up the planet the way we have is not going to do that. I think it’s a great catalyst for reflection and action. And with the environment, it’s kind of overwhelming the state that we are in, and I think the thing about having children is it makes you realize all these things and it also makes you say, 'Okay, what’s the thing that I can truly attack?' And I make a joke, but it’s not really a joke and it sounds so silly when you are talking to international people when you talk about composting, but it’s something that is manageable in my household with managing three kids and running my house the best I can with 24 hours in a day. It’s something I know we can accomplish... I drive a bio-diesel car. I try to set goals that are achievable and then once we get those down, find some more goals that are achievable and keep going a little bit, as opposed to saying, 'I am going to be completely waste-free in my house,' and all this kind of stuff. It’s just a little bit at a time. And if we all did a little bit at a time, it would just be so impactful."

Julia Roberts on being a mother:

"It's just the best thing ever. Yeah, it’s definitely a challenge. Three kids, I cannot believe I have three children! I always wanted to be a mother and I have a great mother. It’s the most fun thing, but yeah, it’s difficult. It’s a tough, tiring thing. But I’m really lucky that I was able to have 20 years of a career before I had my kids, so I don’t really feel torn this way and that way. I feel very content to be at home and be a mom and have a very sort of simple day-to-day life and occasionally get to go off and work and fill that side of my creative process."
