Trivia, insights & behind the scenes
The 'yeong' in San-yeong's name references Korean shamanic concepts of spiritual possession, while the five demons correspond to traditional Korean gwishin categories subverted for modern class critique.
Kim Tae-ri performed her own contorted possession movements after studying modern dance; director Lee Jeong-lim kept cameras rolling through her exhaustion to capture genuine strain.
