Interview from
Aperture that's worth a read.
And given today's news about Jean-Luc Godard, here's Klein from that interview on Godard:
"Klein: I dream about a million things. It’s incredible. I had a dream recently, and I still don’t know whether it was a dream or not. It was about New York. Jean-Luc Godard was there, it was a Saturday, and there was an art opening. The people there were very friendly, and Godard was so, so nice, and also friendly. He was exhibiting his paintings, and people were saying, “Oh Jean-Luc, you have to come to my studio—I have some nice paintings to show you.” And he would say, “Of course!” which is so little like him. It was so precise, and everybody was the way that they should be. It was Godard being a nice New Yorker. He’s a prick, actually; I know him pretty well."
