Since One Direction went on hiatus this time last year, Harry Styles has been keeping relatively out of the public eye - which might be because he's been busy filming his debut movie role in Dunkirk.
We already know he had to cut his hair for the film and that it was directed by Christopher Nolan, stars Tom Hardy, Cillian Murphy and Mark Rylance, and tells the story of the Dunkirk Evacuation - but other than that, we didn't really know much.
Until now, that is, after the second official trailer for Dunkirk dropped this afternoon - and features a the One Direction star in army uniform.
This comes as yesterday, a poster surfaced online ahead of the film's release next year, and One Direction fans were speculating heavily about whether it was the back of Harry Styles's head that featured.
In the poster, a solider stands in uniform on the coast by a rough sea, looking into the distance where a fire rages. Planes fly above his head, it's very atmospheric - and One Direction fans are already speculating about whether the solider's back of head is Harry Styles.
The film will tell the story World War II, where a large number of Allied Belgian, British, and French soldiers were cut off and surrounded by the German Army, and rescue mission Operation Dynamo - otherwise known as the Dunkirk Evacuation - occured between May 26 and June 4 to save them.
