Feng Lu’s “L’histoire d’un Accident”, presented in Avignon 2025, offers a layered exploration of theatrical space inspired by Henri Lefebvre’s theory of spatial production. The play unfolds through a play-within-a-play structure, blending backstage conflict, parody, and audience disruption to challenge the boundary between fiction and reality. A planted “spectator” blurs the line between performance and life, turning spatial ambiguity into a central aesthetic strategy. Rather than seeking clarity, the production invites audiences to dwell in uncertainty, where ambiguity becomes an essential part of how space is experienced, performed, and emotionally understood.
