Christopher Nolan doesn't do anything by half measures, and that includes just showing off part of his newest film. If you want to get the first real look at Nolan's World War II epic Dunkirk you'll have to check out very special screenings of a very special movie. Since Nolan has an established love for 70mm IMAX cameras, he shot a significant portion of his new movie with them, and if you want to check out seven minutes of the movie you'll need to find one of the few theaters that are showing Rogue One: A Star Wars Story in that format.
While Rogue One: A Star Wars Story wasn't shot in 70mm IMAX, it has been converted into that format, though not many IMAX theaters will be showing it in that way. Only a dozen theaters across the US, and one in Canada, will have the 70mm IMAX print of Rogue One. However, if you're lucky enough to have bought your tickets to see Rogue One in that location, Slashfilm is reporting that you're screening will be starting about seven minutes later than the rest, as you'll see seven minutes of Dunkirk. It's possible that the Dunkirk preview will be in front of all IMAX showings, but that's not confirmed. Only the 70mm preview is for sure at this point.
It's a similar to move to what Christopher Nolan did prior to the release of The Dark Knight Rises. Prior to that film's release, the first few minutes of it were placed in front of screenings of Mission: Impossible - Ghost Protocol. In that case, the preview was only shown on 70mm screens, so there's a good chance that will be the case here as well.
Dunkirk will tell the story of real-life World War II soldiers who found themselves stranded on the western front of the war. Thousands made their way to the shores of Dunkirk in hopes of finding rescue.
While Dunkirk promises to be as big a movie as anything Christopher Nolan has done, following the Dark Knight Trilogy Inception and Interstellar, Dunkirk will tell a much more grounded story than we've seen from Nolan in a long time. With it being not just a realistic story, but a real one, it will be a very different experience, though the subject matter deals with a fairly unbelievable event, so there may still be room for the fantastic. Dunkirk is set for release July 21, 2017.
