It's not so much what you learn about Mumbai, it's what you learn about yourself, really. It's a funny old hippie thing, but it's true as well. You find out a lot about yourself and your tolerance, and about your inclusiveness.

I don't feel that I'm explaining the world or teaching people anything. And I'm not trying to be a mirror, showing them what's really going on the world. All I'm trying to do is think of stuff that's funny, just like when I'm kidding around with my friends.

Here's the thing - I'm single, I haven't been married, I don't have kids yet. If I do have kids I would be interested to see them in my life, so here's a movie for kids and I'm in there and I'm supposed to be kind of funny for kids.

It's funny, because there are so many stereotypes out there about actors and movie stars in general, but I've had a great opportunity to meet a lot of them, and maybe it's just because they don't behave that way around me, but I rarely see that kind of abuse of power.

With my boyfriend, we can make sexist jokes to each other because we know it's absolutely not true. If I get home from a long day and he says: 'Go on, get in the kitchen,' it's funny because we know it's not our lives.

But I think Kiss Kiss, Bang Bang really got that thing where, if a movie reads really funny and then has some dramatic or violent or sinister stuff in it, you can't forget that primarily it has to be even funnier than you read it or that other stuff doesn't work.

We've seen some insane signs: 'Is that a loaf of bread in your pocket, or are you just happy to see me?' Funny stuff along those lines. Very original. One just said, 'I will do unspeakable things.' I thought that was very interesting - and mildly terrifying!

I tend to play characters that I can infuse with certain kinds of humour. Even the baddest guy can be funny in his own particular way. I want the audience to engage with the character on some deeper level so that they leave the cinema still thinking about him.

To be thrown onto the stand-up stage is an experience that you cannot fathom until you're actually there, because there's no place to go, and everyone is looking at you and you can't even see them because of the lights. And yet you have to manage to start talking and be funny on top of it.

It's funny, but to me, when you go to a concert hall and hear electronic pieces from the '60s, I think they sound really dated. But when an orchestra plays a piece from that period, and it's going to sound different every time, it feels more modern to me.
