Because there is so little room for expression otherwise, a lot of people love cinema because they find it a way of expressing themselves.
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.
Usually people like to categorise artists. With my films, I categorise people: if I know which one of my movies you like, I can tell which kind of a person you are.
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.
From 7 in the morning to 11 at night, I was reading. I don't think one can find any other time in one's life to be left alone so much to read in peace like that.
In Afghanistan, this is the problem, because everybody holds a piece of that mirror, and they all look at it and claim that they hold the entire truth.
Rumi, who is one of the greatest Persian poets, said that the truth was a mirror in the hands of God. It fell, and broke into pieces. Everybody took a piece of it, and they looked at it and thought they had the truth.
I was in jail four and a half years. When I came out, I continued the same struggle against injustice, but instead of using weapons, I began to use art and cinema.
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.
When I came out, and for many years afterwards, it had become a habit for me to sit and read and read and read, like an obsession. I would take 20 books, and not come out until I'd finished them. It took me a while to change that habit.
I myself had to grow a longer beard and Afghan clothes. I was in danger of being kidnapped by smugglers, though I didn't know it at the time.
Five years ago, Samira did not want to continue in the regular school system in Iran. To help her with her education, I set up a home school. It wasn't just for my family, it was open to other friends.
From my films, you can at least learn about Iran, you can get a sense of the history and the society. But no such films have been made about Afghanistan, so you really can't know much about it.
Afghan society is very complex, and Afghanistan has a very complex culture. Part of the reason it has remained unknown is because of this complexity.
