Guillaume Langlois directed the trailer and video design for the show Le Plan Astral, a creation by Une Autre Compagnie de Théâtre. Presented at the M.A.I. and MainLine Theatre in 2017, this docu-theatre features four protagonists exploring the world of clairvoyance and the paranormal in search of answers about destiny and belief. The videos integrated into the show, made from sequences filmed during consultations with clairvoyants, offer a visual immersion in this introspective quest. The trailer, meanwhile, captures the essence of this esoteric exploration, blending humor and reflection on contemporary spirituality.
