Guarda su Altadefinizione. 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.
