It is 2016. Christo is already over 80. Walking on Water is a temporary promenade on Lake Iseo in Italy. It is his first project since the death of his wife and co-author Jeanne-Claude, with whom he lived for almost half a century. The grumbling old man and his brutal nephew and manager Vladimir bicker with officials, yell at the technical crew and curse the bad weather. In the meantime, a three-kilometer plastic walkway grows gradually on the lake. Before the opening, they will cover it with orange cloth. Andrey Paounov, the director of this film, does not try to get into the artist's head - Christo barely talks about his creative method here. Apart from one moment where he reveals that this water walk of his is devoid of biblical allusions. This installation is a work of art that has a purely emotional nature. We can feel the joy from the sensation of the water on the lake, the sun, and the wind. There are some particular moments in this documentary that have more to say about art than lectures of art critics. For example, when the camera stops at the portrait of Jeanne-Claude, or in the desert, where the artist is crawling in the sand around the prototype of his new installation.
