Gerhard Richter Painting, about one of the world’s greatest living painters, is a thrilling document of Richter’s creative process, juxtaposed with intimate conversations (with his critics, his collaborators, and his American gallerist Marian Goodman), and rare archive material. From our fly-on-the-wall perspective, we watch the 79-year-old create a series of large-scale abstract canvasses, using fat brushes and a massive squeegee to apply (and then scrape off) layer after layer of brightly colored paint. This mesmerizing footage, of a highly charged process of creation and destruction, turns Belz’s portrait of an artist into a work of art itself.
