There's an 800 kilometer border between Iran and Afghanistan.

The question in their minds was, why did the outside world, and particularly the Western world, produce all these landmines, and send them to Afghanistan? This business must be stopped. It's a dirty business to produce such a horrible device.

Do you know that every day, 10 people in Afghanistan are injured by landmines? It will continue for the next 50 years, because the country has the largest number of landmines in the world.

I wanted to be left alone to live my life, so it was very easy for people to pretend that they were me.

If I make two films in a year, they'll be different. This is my style - I can't have just one way.

But also, there are no films being made about Afghanistan.

When we began filming, these people had legs, but as we were filming, they had been injured and they were brought to the hospital to have their legs amputated, and that's where we found them and asked them to come and be part of the film.
