The One Direction member was spotted donning British World War II military dress – and his new short haircut! – while on the set of his new movie, Dunkirk. The upcoming film from writer and director Christopher Nolan tells the true story of the evacuation of the French city during World War II’s Battle of France in 1940. Filming occurred 76 years after 338,000 French, Belgian and British troops were saved from the surrounding German soldiers – the largest military evacuation in history. While Styles’ role in the film is being kept under wraps, he was spotted costumed in a British army uniform. His character also appeared to be wounded in some shots, with a bloodied bandage surrounding his hand. RELATED VIDEO: Who Is Cuter: Harry Styles or a Puppy? A fleet of WWII battleships and army-clad extras joined Styles for the action-packed day of filming. A historic French T-47 class destroyer called the Maillé-Brézé was shipped in specifically for the filming. Styles cut his signature long locks prior to filming, sharing an Instagram photo of his chopped-off ponytail that he donated to charity. Although he was spotted en route to filming earlier this week, his hair was hidden under a hat. Dunkirk also stars Tom Hardy, Cillian Murphy, Kenneth Branagh and Oscar-winner Mark Rylance, and is set to hit theaters on July 21, 2017.
