If a twig is bent in the forest, is it art? It is in Rivers and Tides: Andy Goldsworthy Working With Time, director Thomas Riedelsheimer’s account of the Scottish environmental artist’s substantial life and fleeting work. Goldsworthy uses natural objects to make sculptures, many of them highly mutable—and therefore preservable only through photography. Thus Riedelsheimer becomes the artist’s collaborator, capturing on film constructions that will soon vanish in the rain, the wind, or the sun. For this lyrical documentary, the filmmaker followed Goldsworthy as he made ephemeral things from branches, leaves, and even ice, observing the artist’s intuitive process, the fragile beauty of the resulting pieces, and the natural grandeur of the terrain in which he works. Much of the film was made in the beautiful area around Goldsworthy’s home village of Penpont, but it also includes footage of the artist at New York state’s Storm King Arts Center. It screens at 12:30 p.m. at the National Gallery of Art’s East Building Auditorium, 4th and Constitution Ave. NW. Free. (202) 842-6799. (Mark Jenkins)
