Harry Styles: Is it ok to cry about the film I'm starring in?
Harry Styles' first acting role? It's a strange one!
Buzz Lightyear in Chitty Chitty Bang Bang of course.
Not content with just being one of the biggest pop stars on the planet, Harry Styles is making his cinema debut in Christopher Nolan's emotional war movie, Dunkirk.
Harry's big-screen debut is already picking up rave reviews from critics, but as a newbie in the movie business, the Sign Of The Times chart-topper is uncertain how he's meant to respond to the finished film.
It got me a few times, there were a couple of emotional bitsHarry Styles
"The first time I watched it, I hadn't seen how Christopher Nolan had put things together," Harry told Nick Grimshaw when he visited this week.
"So I was watching to see what the story was.
"Then I watched it at the premiere in London and it got me a few times, there were a couple of emotional bits where I didn't know if it was OK to cry at a film I was in."
Harry plays a small part in the film, but his superstar status did not guarantee him a part in the production. He had to audition like every other actor in the movie.
Everyone in the room was people I鈥檇 seen in moviesHarry Styles
"I did a tape and sent it in," he told Nick.
"I did it with the casting director in America and flew back to the auditions in London - which was a bit weird."
Harry stars alongside Fionn Whitehead, Tom Hardy, Cillian Murphy and Mark Rylance in Dunkirk and admits he was a little bit star-struck when he first met the rest of the cast.
"You walk into a room and everyone in the room was people I’d seen in movies," he said.
"It's so weird because you do it and then you go home and obsess over whether it was good or not, so it's a really strange thing."

Wanting to blend in with his acting colleagues, Harry also revealed he toned down his pop star fashion while working on Dunkirk.
Walking onto the set, it was so overwhelmingHarry Styles
"I purposely went in a beanie hat and a jumper to maybe try and blank-canvas things down a little bit," he told Nick.
He was also blown away by the size of the production when he started filming his scenes.
"Walking onto the set, it was so overwhelming," he added.
"Trying to imagine something of that size and then when you actually see it, it is insane."
And despite having performed in front of millions of fans as a solo star and as part of One Direction, Harry admits he was a little bit freaked out when he watched himself on the big screen.
"I don't like it [watching myself]," he said. "It's a bit weird."
Dunkirk is released in the UK on 21 July 2017
