Taken as a whole on the 'Dunkirk' Blu-ray's bonus disc, the individual featurettes from each section of 'The Making of Dunkirk' add up to an in-depth behind-the-scenes documentary that is longer than Dunkirk itself and that covers all aspects of the film from its inception to post-production and scoring. An impressive roster of crew describe such technical challenges as filming on water, designing camera mounts to attach the heavy IMAX rigs to vintage airplanes, rebuilding the "mole" that extends into Dunkirk's harbor and melding aerial footage with inserts shot on a soundstage with a gimbal rig (and yes, that's Nolan himself operating the gimbal). The extras also note the exceptional support and assistance rendered by the local Dunkirk authorities and by Britain's Association of Dunkirk Little Ships, which supplied many of the actual vessels from the 1940 evacuation for use in the film.
