I'm good at not laughing. It's not that I don't want to. I'm too old and experienced.

Emily [Blunt] is such a giggler, she has such a positive life force about her and she's so giggly in a naughty sort of schoolgirl way that it kind of brings out the worst in you, you just love making her laugh. And also Nick Stoller has one of the best laughs. It's so infectious and whenever he laughs at something you do, it's like giving us a reward.

I usually do get to play the very sweet, charming roles... but I'm not an obvious kind of villain.

I love gay Mardi Gras in Sydney, which is a big parade, a big march that thousands and thousands of people participate in. And there's one little group... well it's not little, it's got hundreds of people marching, and they're all very sweet, middle-aged and elderly people who are the parents of gay children who are out and proud.

One of the things you learn at drama school is not to play the result, but just to play the moment.

I'm a nice middle-class girl in real life, and I'm a mom and a grandma, and I usually play sweet characters.

The thing about being an actor is that every new job is a new challenge. Sometimes you'll have a shot, and it doesn't work. Sometimes it'll work better than you expected.
