You have to trust that Christopher Nolan knows what he’s doing casting a former boy band member in his next big movie, but Harry Styles’ role in Dunkirk is a curveball nonetheless.

Yesterday, we got a better look at his role in the first full trailer, and it seems as though he’s playing a minor/supporting character - a young soldier trapped in Dunkirk.

Styles’ enormous fan base are obviously delighted with his foray into Hollywood, but a little confused about the film and the true story behind it:

Dunkirk is, of course, a city in northern France, and the film centres on the rescue of hundreds of thousands of Allied soldiers from its harbour during World War II, when the German army had them surrounded.

The lead actors in the film have been singing Styles’ praises.

“Harry Styles is great," Cillian Murphy told the Radio Times.

"I had very few scenes with Harry but we got to hang out and I've got to say he's a great, great kid, and really, really funny.

"Above all,” he added, “Chris Nolan knows talent and would have cast Harry for a reason.”

Mark Rylance echoed this, telling the Standard: “He seems remarkable ... one of those people [who has] — Sean Penn has it too — a kind of panache. I look at them and think, ‘How did you get that? How do you get so that life is easy?’ But he has got a lovely, lovely character. It’s a gift.”
