Ross Perry visits the ever-iconoclastic auteur Paul Schrader during the making of his 2017 masterpiece First Reformed. On set and at home- where, for his own pleasure, he continues to work and rework his previous films- Schrader reflects on the highs and lows of his legendary career, the challenges and rewards of slow cinema, and the influences and experiences that continue to shape his approach to filmmaking. With this insightful portrait of one of his filmmaking heroes, Perry captures an artist who is continually at play, intentionally provocative, and never less than vital.
