Ten years after the passing of his wife and partner Jeanne-Claude, Christo sets out to realise The Floating Piers, a project they conceived together many years before. Walking on Water is an uncensored and “cinéma verité” look into Christo’s artistic process, from the inception to the completion of his latest large-scale art installation. And yet, this intimate portrait of a man chasing a dream happens on the backdrop of the epic madness of it all — the complex dealings that merge between art and state politics, engineering challenges and logistical nightmares, and the sheer force of nature, captured through breath-taking aerial views and fly on the wall cameras. So, as we watch the dream unfold, we get to know the man chasing it: Christo.
