Some of the most compelling sequences in Wright’s documentary consist of the artist’s reflections on perception, perspective, and space. After a painful breakup with his longtime partner, Peter Schlesinger, Hockney made a series of etchings based on Wallace Steven’s poem, “The Man With the Blue Guitar,” which was in turn based on Pablo Picasso’s famous 1903-04 Blue-period painting, “The Old Guitarist.” Hockney was drawn to the poet’s insistence on “things exactly as they are,” using his etchings to play with realistic and illusionistic depictions of space, all within the emotional frame of the artist’s life and relationships with others.
