I'm not an abstract artist; I leave that to others. To me, abstract art ended with Kazimir Malevich's 'Black Square.' To continue it is senseless.

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.

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.

We need less perfect but more free films.

I'm not so much in the future as always in the present. The future always takes care of itself. What I do now with my video camera, it can only record what is happening now. I am celebrating reality and the essence of the moment. And that's the greatest challenge that I have.

I'm not an abstract artist; I leave that to others. To me, abstract art ended with Kazimir Malevich's 'Black Square.' To continue it is senseless.

Once you change the technology - from a film camera to a video camera, or from an 8-mm camera to 16 mm - you change completely the content. With 8 mm, a leaf on a tree will be made up of maybe four grains. So it's very impressionistic, almost like Seurat. If you switch to 16 mm, the technology gives you hundreds of grains on that leaf.
