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

The style depends on the subject.

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.

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

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.

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.

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