Why Admitting You "Don't Know" Can Land You the Job (Like It Did on 'Whalefall')

How do you adapt a novel that takes place almost entirely inside the stomach of a sperm whale? For writer-director Brian Duffield and Pulitzer Prize-winning author Daniel Kraus, the answer started with admitting they didn't know how to pull it off. In this episode, No Film School's GG Hawkins speaks with Duffield and Kraus about bringing Whalefall, starring Austin Abrams and Josh Brolin, from page to screen. They discuss the scientific research behind the story, the challenges of adapting a novel with dozens of flashbacks, building practical whale interiors with Wētā Workshop, and directing a physically demanding survival thriller. Duffield explains why acknowledging uncertainty helped build trust with studio executives and how surrounding himself with collaborative crew members made an unusually challenging production possible. Plus, Kanopy's Aaron Spears and Matt Lewis stop by to discuss the Crypt Collection, practical effects in horror filmmaking, and the movies that continue to scare them.
