Christo and his late wife/partner Jeanne-Claude (1935-2009) created some of the most visually breathtaking art installations of the postwar era, including Running Fence in Sonoma and Marin counties (1976), Wrapped Reichstag in Berlin (1995), and The Gates in Central Park (2005). The Floating Piers—an ambitious effort to create the effect of walking on water via a 3-kilometer walkway over Lake Iseo in Northern Italy—is Christo’s first large-scale project since Jeanne-Claude’s passing (the two conceived of the idea together). Filmmaker Andrey M Paounov has rare access to Christo’s process, from inception to completion of the installation: thorny negotiations with local government, engineering challenges, crowd control, logistical nightmares and the sheer force of nature, captured through breathtaking aerial views and fly-on-the-wall cameras.
