Harry Styles is completely covered in mud while shooting a scene for his upcoming film Dunkirk on Wednesday (July 13) in Urk, Holland. The 22-year-old One Direction singer is starring in the film, which is being directed by Christopher Nolan. The movie follows allied soldiers from Belgium, Britain and France who are surrounded by the German army and evacuated during a fierce battle in World War II. Harry was also spotted filming scenes by the water last week. Dunkirk is set to hit theaters on July 21, 2017.
