Corinna Belz's award-winning documentary is a portrait of artist Gerhard Richter, widely considered among the world's most important living painters. With the perspective of a fly on his studio wall, we witness his dramatic process of creation, balanced with rare archival material and interviews that share the thoughts of his collaborators and his critics. His career has been a high-wire balancing act between eye-popping, colourful abstractions -- seen in start-to-finish construction throughout much of the film -- and enormously famous photorealist portraiture. He has also been an influential essayist on the subject of art-making and its place in the world. Famously cranky, iconoclastic, and media-shy, Richter illuminates the deep fissures in the contemporary art world.
