After giving relatable instructions on mundane topics in his successful series How to with John Wilson, the American documentary filmmaker and producer struck festival gold with his first feature-length documentary. The History of Concrete takes the omnipresent material as a thematic prism to explore very different kinds of structures, industrial, sociological, and emotional. After premiering at Sundance and packing movie theaters at Copenhagen's CPH:DOX, the tragicomical doc is now at Visions du Réel. Just after the Q&A of his sold-out screening, John Wilson found time for an interview with Lidanoir, talking the challenges of independent filmmaking, his desillusioned feelings about the titular material, and making the most unfunny things comical.
