The Life of Sean DeLear is a vibrantly multi-faceted, buoyantly propulsive documentary portrait of this irresistibly charismatic one-off — sketched in celebratory but commendably clear-eyed style by writer-director Markus Zizenbacher. There can be very few people better qualified to do justice to this particular tale. Zizenbacher befriended DeLear — born Anthony Robertson in Simi Valley, an obscure California backwater — after the latter relocated to Vienna in the early 2010s.

Art dealer Salvatore Viviano and director Angela Christlieb embark on a search for the lost artist collective Gelitin, which since the 1990s has shattered the borders of "good taste" again and again with extravagant actions and installations. Interviews with old companions and artist friends in the U.S., Europe, and Asia are linked with anarchically montaged Gelitin archive material: intense, transgressive, experimental, gaudily colorful, funny, and virulent.
