I felt I grew up when I was about 28. I feel pretty much the same. I get reminded when I look in mirrors that I am not. Hopefully, you keep growing and keep planning things as you go along.

It's unusual to spend even three full hours away from my newborn baby, it's like a piece of my body is back in the hotel room, and it does feel strange. But I love my work, though, it's not just a job for me, punching in my time card. I've always loved what I do, it's what makes me happy and I figure if I'm happy I'll be a good Mum too.

I think every time you take on a new role, you're trying to help find that voice and you add your own bits and pieces along the way but with Noah [Baumbach] it's already done.

I don't know that any woman could ever not think about that at some point - even making the choice not to do it and getting to the place of peace of choosing not to be a parent, there would have still been some struggle in between. I'm not a man but I don't think it would occupy their minds as much.

If I have to produce movies, direct movies, whatever to change the way Hollywood treats older women, I'll do it. If I have to bend the rules, I will. If I have to break them, I will.

I think whether you've got children or not you're just more aware of others as you get out of your 20s.
