Interstellar‘s 35mm and 70mm prints played in just 77 markets, compared to 3,561 theaters in its official opening weekend.
Christopher Nolan, like many of his directorial contemporaries, is a proponent of film over digital in regards to how a movie is presented.
Per Indie Revolver, Dunkirk will receive special 35mm and 70mm screenings in equipped theaters on July 19, 2017 – two days before the nationwide (and largely digital) release.
For this reason, Nolan chose to film his latest work, the World War II drama Dunkirk, on 65mm stock.
