Artist Vik Muniz's style is hard to classify (such as painting with chocolate sauce), but his amiable personality is easy to take in this profile. Producer-director Anne-Marie Russell follows Muniz to Chicago and Paris, where his works (enhanced by such things as thread, spaghetti and sugar) are being shown; to Arizona, where he has difficulty photographing a huge “bone” he had fashioned---with a bulldozer---in the desert; and his native Brazil, where he philosophizes. “Art really isn't about what you say,” he muses. “It's about how you say it.” Don Cheadle hosts.
