One of the most beautiful and satisfying of Andy Warhol’s early black-and-white silents, this is a 39-minute portrait of painter Robert Indiana slowly eating mushrooms in a swivel chair, occasionally joined by a cat that doesn’t eat (1963). On the same program, Warhol’s Blow Job, 35 minutes in slow motion showing a young man only above the waist who may or may mot be responding to sexual stimulation below the frame line (1963).
