'Dunkirk' Is Being Shown On 70-Millimeter Film. So What?

The World War II drama "Dunkirk" has been a summer hit at the box office, taking in more than $265 million worldwide since it opened last month. "Dunkirk" was shot mostly on super-high-resolution IMAX cameras, and some theaters around the country are projecting it on large-format, 70-millimeter film.
