Four and a half minutes of Back and Forth (1969):
Almost ten minutes from La Région Centrale (1971):
The entire Wavelength (1967):http://video.google.com/googleplayer.swf?docId=-3009876496807585942&hl=en
With Wavelength one of the starting ideas was to be able to see a zoom, to experience a zoom from a kind of analytical “inside a zoom” position, and it seemed to me that could not be fast. I thought it would be interesting to have it big enough so that it is monumental, that is weight in a way, and so it ended up being 45 minutes, but it could have been 15 minutes.~Michael Snow, from Weathering the Creative Storm: An Interview with Michael Snow
P.S. We are back to 36 degrees and rain. Snow is disappearing.
