If you look where kids are spending time on the Net, they may have all the information in the world, but they're not accessing it.

The thing about documentary is that you don't really choose your subjects: they come and grab you out of your bed.

I'm in the communications business.

I often go out on the street with my camera and ask questions.

The thing that upsets me is the ubiquitous use of reward technology, which uses our evolutionary biology against us.

Sometimes you have to put back in the community.

There is nothing wrong with Facebook in itself, except that it is not a very good tool to express the quality of your relationships.

What is the point of teaching how to analyse a poem or a piece of Shakespeare but not to analyse the Internet?

I love being in real life, and in particular, I like being with young people.

I like the accidental nature of being in the real world.

There's something about actors - not stars, but actors - if they have the character, and someone is pushing and shoving them to be the best they can be, they enjoy that.

I've discovered my Jewishness late in life. And I've really enjoyed exploring that world.

I've liked being Jewish in America - there's a secular version of Jewishness there that's more about bagels and jokes than going to synagogues.

I hope that every film I make has something to offer in the area of making people feel either vindicated or different in terms of who they are.

We need to be much more robust consumers.

This is a culture filled with perfect images of women and perfect images of movie actresses, and most people can't live up to them.

I've always been interested in exploring difficult subjects for the mainstream.

Everything serious in the world is well approached by humour. It's a powerful and often quite subversive tool. I suppose there is an argument that could be made against me for being frivolous, but I do think a laugh is a very generous thing to give.

Each January, nearly half a million people visit the small town of Saundatti for ajatre or festival, to be blessed by Yellamma, the Hindu goddess of fertility.

Girls from poor families of the 'untouchable,' or lower, caste are 'married' to Yellamma as young as four. No longer allowed to marry a mortal, they are expected to bestow their entire lives to the service of the goddess.

I absolutely don't want to suggest that women are unreliable because we're mothers - on the contrary. But the question of who brings up the kids has a material effect on all women's careers.

The devadasis have a multilayered story, a story in which poverty, deprivation and injustice against women is central - but what has happened to them is absolutely an outcome of imperialism and the impact of British rule in India.

A white woman with a camera in the Devadasi belt of Karnataka is not inconspicuous... it took time for these women to believe that I was not an official, carrying the threat of fine and imprisonment.

When I was 13, I had a weekend job at the Photographers Gallery Bookshop in London.

Not many young women of my age have been lucky enough to have had a wonderful mentor in their life.

I've lost count of the plane tickets I've had in my pocket for people's weddings and other celebrations which I've had to tear up because I was making a film. How many things like that can you miss and still be in people's lives?
