Filmed in 2000 at Richard Serra’s Manhattan studio, the artist describes the various tools and conceptual strategies he has used throughout his career when working with lead and steel. Serra discusses his early focus on the nature of the art production process itself which resulted in his writing a Verb List (1967-68).
Multiple lead works that resulted from Serra acting out the Verb List are shown through archival images. Serra’s invention of a tool that twisted sheet metal around a wheel enabled him to shape steel in a new way—from the inside out. Torqued Ellipses (1996-97), which resulted from this process, are shown at Dia:Beacon in 2004.
