"All That Breathes" won top prizes at Sundance and Cannes for its portrayal of two brothers in New Delhi who dedicated themselves to rescuing birds from the hazards of the polluted city. Pure Nonfiction host Thom Powers talks to director Shaunak Sen about how he scrapped his first year of filming to start over. Shaunak discusses the contributions of cinematographer Benjamin Bernhard ("Aquarela") and editor Charlotte Munch Bengtsen ("The Truffle Hunters") in the creation of one of the year's most visually striking films.

 "All That Breathes" is now playing on HBO Max.
