Probably not very relevant to this thread, but in the film, ignoring the role of Indian soldiers in the Dunkirk battle has been criticized by many people.

Christopher Nolan's epic World War Two film, Dunkirk, which tells the story of the mass evacuation of Allied troops from the northern coast of France in 1940, has been getting glowing reviews in India.
But many are glowering over Nolan turning a blind eye to the role of Indian soldiers in the battle. The Times of India wrote that their "significant contribution" was missing from Nolan's "otherwise brilliant" work. Writing for Bloomberg View, columnist Mihir Sharma said the film "adds to the falsehood that plucky Britons stood alone against Nazi Germany once France fell, when, in fact, hundreds of millions of imperial subjects stood, perforce, with them".
Few can deny the role of the subjects. Some five million Commonwealth servicemen joined the military services of the British empire during WW2. Almost half of them were from South Asia. Indian soldiers played a key role in major battles like Tobruk, Monte Cassino, Kohima and Imphal. A multinational force of British, Indian and African units recaptured Burma (Myanmar) for the Allies.
What is well known, she told me, is that four companies of the Royal Indian Army Service Corps, including a unit of the Bikaner State forces, served in France during the campaign on the Western Front, and some were evacuated from Dunkirk. Among them were three contingents of the Royal Indian Army Service Corps. One contingent was taken prisoner by German forces.
"They weren't large in number, maybe a few hundred among hundreds of thousands, but their appearance in the film would have provided a good reminder of how utterly central the role of the Indian Army was in the war," he told Slate.
"Their service meant the difference between victory and defeat. In fact, while Britain and other allies were licking their wounds after Dunkirk, the Indian Army picked up the slack in North Africa and the Middle East.

Otherwise said to be a good movie...though I am yet to see it.
