For his segment, "Siang Sawan" ("Luminous Sound"), Pen-ek chose to interview blind pianist Sila Namthao, letting the musician perform some of the songs composed by the king, and talk about his inspirations and life. "We don't know the King well enough to make a film about him, so this is more like a present that someone would give him on a royal visit," Pen-ek explained in an interview. "If everyone were blind, perhaps our desires would be fewer and more simple. This has echoes of the king's sufficiency theory, and I hope the film will bring it home to the audience," Pen-ek said.
