Troublemakers: The Story of Land Art is a 2015 American documentary film directed by James Crump. Troublemakers chronicles the history of land art in the 1960s and 1970s, when a group of radical New York artists began producing earthworks on a monumental scale in the desert spaces of the American southwest. The film follows the enigmatic careers of artists who use the earth itself as their primary medium, including Robert Smithson, Walter De Maria and Michael Heizer.

Walter Joseph De Maria was an American artist, sculptor, illustrator and composer, who lived and worked in New York City. Walter de Maria's artistic practice is connected with minimal art, conceptual art, and land art of the 1960s.
