For two years, Turner Prize-wining artist Grayson Perry worked behind the scenes at the British Museum to stage his most ambitious show yet The Tomb of the Unknown Craftsman. In a major departure for both artist and Museum, Perry was given free rein to choose whatever he wanted from the Museum s collection of more than 8 million objects gathered from around the world. He also made his own works of art from his trademark ceramics to sculptures, tapestries and even a working motorbike. The resulting exhibition was as if the visitor had stepped into the treasures of a mysterious civilisation a civilisation built entirely around the obsessions of Perry himself. Granted unique access over a two-year period, this film paints a revealing portrait of Perry s creative process, and even follows him on a motorbike pilgrimage to Germany as he explores the artworks, ideas and motivations that lay behind his British Museum show.
