guardian | “I’ve always loved films that approach sound in an impressionistic way and that is an unusual approach for a mainstream blockbuster, but I feel it’s the right approach for this experiential film,” said Nolan. “Many of the film-makers I’ve admired over the years have used sound in bold and adventurous ways. I don’t agree with the idea that you can only achieve clarity through dialogue. Clarity of story, clarity of emotions — I try to achieve that in a very layered way using all the different things at my disposal — picture and sound.”
One scene in which some viewers struggled to hear dialogue featured Michael Caine’s character revealing key information to Jessica Chastain’s from his hospital bed. “We are following the emotional state of Jessica’s character as she starts to understand what he’s been saying,” said Nolan. “Information is communicated in various different ways over the next few scenes. That’s the way I like to work; I don’t like to hang everything on one particular line.”
