Legendary among filmmakers who have witnessed it, White Heart is a symphonic exploration of cinematic meaning that unfolds through a multi-layered, contrapuntal audio-visual montage of numerous and disparate ingredients: images of city streets, verdant forests, and ocean waves; bits of film leader and editor’s marks; oblique footage of Barnett’s colleagues Larry Gottheim and Saul Levine; an interview with two young missionaries; the sounds of classical music, typewriters, video tone, and, most centrally, a brief passage from Ludwig Wittgenstein’s Philosophical Investigations. These elements and more emerge and re-emerge like musical motifs, continuously and meticulously altered through processes like bleaching, staining, and multiple print generation, dramatically extracting the formal particularities of the Kodachrome reversal print.
