Christopher Nolan’s directorial outputs have become synonymous with summer blockbuster entertainment. Along with Emma Thomas, his wife and producing partner, the “Memento” director operates Syncopy, the production company whose logo shares the distinctive maze design that accompanied much of the promotional material for his 2010 hit, “Inception.” The Producer Guild of America’s annual Produced By Conference featured a conversation with both Nolan and Thomas, moderated by PGA National Executive Director Vance Van Petten at the Wheel of Fortune studio on the Sony Pictures Entertainment campus. Some of the notable excerpts from their conversation are featured below: On Nolan’s directorial debut, “Following”: Van Patten quizzed the pair about their early years, comparing their efforts to make the noir-tinged “Following” after the two had finished their time at university.
