John Cassavetes once said, "Film is, to me, just unimportant. But people are very important." And it's evident in his work that it wasn't cinematic trickery he was concerned with, rather, telling emotionally penetrating stories that expose the human condition and the pain inherent in love, relationships, and questions within the self. Coming from an acting background, Cassavetes was a true actor's director, understanding the important of a nuanced performance that was as genuine as it was full of conviction. He always managed to evoke raw and genuine work from his actors—at whatever cost and by any means. A passionate man of extremes, he was never short of fervor and energy—whether or in front of or behind the camera. Cassavetes believed that, "We are people already, so all we have to do is be someone in a given situation." And today, The Criterion Collection has posted a slideshow of wonderful images showcasing Cassvetes at work from the set of Shadows to A Woman Under the Influence—and there isn't a single one that isn't wonderful.
