Luca Guadagnino‘s Suspiria is “the most brilliantly scary film I have ever seen,” actress Jessica Harper wrote on her private Facebook page last weekend. “Luca’s Call Me By Your Name does not prepare you for it, but throws into relief the director’s brilliance and versatility,” she added. Harper has a small role in Suspiria, of course, so she’s not processing the forthcoming Amazon release from an impartial perspective.
