revealed that his character's name is Tommy.
Behind the scenes photographs of the star showed him covered in mud and blood as he embraced his war-torn character, with one photo suggesting that his character might injure his hand in the storm of battle.
Filming has taken place in several countries as they try to remain faithful to the real story of what occurred during the 1940 evacuation - with air raid scenes being filmed in Urk, Holland, pictures of the leading cast members being covered in dirt in Weymouth, Dorset and scenes on the beach of Dunkirk itself.
The mission is one of the most incredible stories of World War II, which Winston Churchill described as turning a "colossal military disaster" into "a miracle of deliverance."
In order to take on the role, Harry cut off his iconic long locks for a shorter do in order to remain faithful to the era of the second World War.
He donated what he had removed to the wig-making charity Little Princess Trust.
Fans at one point threatened to disrupt filming as they flooded Weymouth to catch a glimpse of the star in action.
An insider spoke to Mirror Online and said: “Harry has to have a full-time bodyguard to follow him around because fans have been breaking onto set to see him.”
The Sun Online has contacted representatives for the film to confirm the identity of the actor in the poster.
