It's a very generous culture, American culture. I know you can't generalize 300 million people, but everyone I've met here has been so lovely to me.

Emily and I have some funny scenes where we quarrel and it gets quite heated, the mother-daughter relationship. You know, film mothers and daughters adore each other. And some don't. But how could you not love Emily Blunt? But I think I'm just one of those people who's always discontented.

You learn stuff from every character you play about the human condition that can be quite enlightening.

When you get as old as I am, you kind of believe there's nothing new under the sun, but there's always a fresh way of looking at something. That's why I love working with young people. They remind you of things you used to know and have since forgotten.

To be embraced by Hollywood when I'd been acting professionally for almost 50 years seemed unbelievable. I've been so welcomed in such a warm, generous way - it seemed crazy not to take advantage of it. I hope for another 20 years where I can still keep going.

David Michôd changed my life, quite literally, along with the chaps at Sony Pictures Classics. That's what set me on my way. I thought we did good work and had a good film, but when it was so praised at Sundance that year that's what really started the ball rolling. We all paid our own way to Sundance.

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.
