Warhol's early film portraits are far tenderer ventures than, say, his silkscreened "portraits" of Marilyn and Jackie. Here time-film time, slowed considerably but never actually still-allows the image to emerge from the (silky) screen in its considerable permutations. And with the image evolves the personality. Eat is Warhol's meditation on Robert Indiana's meditation on eating a mushroom. Stunningly shot in sunbathed black and white, the image, like the mushroom, appears self-regenerating.
