Selby with Darren Aronofsky, who directed the film adaptation of Requiem for a Dream, in 2000. “I needed to make a film from this novel,” Aronofsky wrote, “because the words burn off the page. Like a hangman’s noose, the words scorch your neck with rope burn and drag you into the sub-sub-basement we humans build beneath hell.” Selby felt that Aronofsky’s film did justice to his work. After seeing it at the Cannes Film Festival he burst into tears. “It was so moving,” he explained. “It is such an emotional film, so powerful.” Requiem for a Dream is widely regarded as one of the best novels ever written about substance abuse. Selby’s profound understanding of addiction was surpassed only by his will to overcome the disease in his own life. The month before he passed away, doctors offered him morphine to help relieve his pain—but he refused. He wanted, he said, to retain his clarity.
