Bulgarian director Andrey Paounov's documentary chronicles famed environmental artist Christo's first major project after the death of his wife and long-time collaborator Jeanne-Claude. With the help of his logistics team, he overcomes numerous challenges to realize his 2016 masterpiece "The Floating Piers": a surreal yellow floating walkway on Italy's Lake Iseo.

"There's some dry in "Walking on Water," though not much. There's a fair amount of wet. As for joy, that there is in abundance."
