The British people, or the Britons, are the citizens of the United Kingdom of Great Britain and Northern Ireland, the British Overseas Territories, and the Crown dependencies. British nationality law governs modern British citizenship and nationality, which can be acquired, for instance, by descent from British nationals. When used in a historical context, “British” or “Britons” can refer to the Celtic Britons, the indigenous inhabitants of Great Britain and Brittany, whose surviving members are the modern Welsh people, Cornish people, and Bretons. It may also refer to citizens of the former British Empire.

Which is a shame because the movie had an excellent chance to make a statement had it been willing to go off the rails a little bit (pun intended) and put some shading on these characters.
