Every few years, there comes a film that makes a trip to the theater an event, an experience. These films that I speak of aren’t necessarily the highest grossing movies at the box office, nor are they always the best of their given years. No, these are the films that demand we watch them not just at the theater, but in a certain way at the theater. These are the films that become less when we watch them on a phone, a tablet, a computer, a television, even a standard movie theater screen. Love it or hate it, Avatar is one such film. Gravity is another. In the case of these two films, the theatrical and 3-D experiences unlocked their true potential and elevated them. Enter filmmaker Christopher Nolan, who has sought to provide an unparalleled theatrical experience with his penchant for shooting on film and in the IMAX format. His ambitious World War II picture Dunkirk offers just that; in the IMAX 70mm format, its immersion and intensity are unmatched, though its coldness does hold emotional investment at bay.
