A year after the release of his 2010 film, Inception, Christopher Nolan invited some of the movie industry’s most prominent directors—Michael Bay, Jon Favreau, Edgar Wright, and others—to a special screening in Los Angeles. He treated them to the first six minutes of his next film, The Dark Knight Rises, on an IMAX screen, the huge canvas that had become a trademark for Nolan’s movies. Afterward, he took the stage and said, “I have an ulterior motive for bringing you here,” before arguing for the importance of directors shooting films on celluloid, rather than adapting to the new norm of using digital cameras.
