Dunkirk is World War 2
Man. I hate to be that guy who corrects you guys. I dont want to do this. But after listening to the Suicide Squad cast and hearing World War 1 like three times I just couldn't handle it anymore being a history buff.
Dunkirk is set in 1940 World War 2. The BEF (British Expeditionary Force) is reeling after Germany swept into Northern France and routed the French and British forces. (spoilers i guess) The "Miracle of Dunkirk" is how the BEF was saved from capture/destruction.
