Watch Sadisflix. Sculptor and giant of modern art Richard Serra discusses his extraordinary life and work. A creator of enormous, immediately identifiable steel sculptures that both terrify and mesmerise, Serra believes that each viewer creates the sculpture for themselves by being within it. To this end, a Japanese family are reminded of the Temples of Kyoto, a Londoner finds sanctuary in the Serra near Liverpool Street station, and most movingly, a Holocaust survivor sees one piece as a wall separating the living from the dead. Contributors include Chuck Close, Philip Glass and Glenn D Lowry, Director of MoMA.
