Since 1950 I have been keeping a film diary. I have been walking around with my Bolex and reacting to the immediate reality: situations, friends, New York, seasons of the year. On some days I shoot ten frames, on others ten seconds, still on others ten minutes. Or I shoot nothing. Walden contains material from the years 1964-1968 strung together in chronological order.

I am very active on the Internet. In 2007, I made one film every day and posted it on my website. That was a 365-day project, really exhausting, but I still put a lot of stuff on - from life, friends, my own life.

An adventurer can always return home; an exile cannot. So I decided that my home would be culture.

The deeper I went into culture, the more confused I got. So I needed something more real. I said, "Okay, from now on, my country will be cinema."

Just as in writing, there are novelistic and sort of pedestrian ways of telling a story, to write a postcard with your little pocket camera and put it on websites. I think that's where the most exciting kind of imagery and content is being recorded and exchanged today.

In the very end, civilizations perish because they listen to their politicians and not to their poets.

As a film-maker and a poet, I feel it's my duty to be an eye and an antenna to what's happening around me. I always felt a solidarity with those who are desperate and confused and misused and are seeking a way out of it.
