One Direction's forthcoming film will show both the band's high and low moments, according to the movie's producer Ben Winston.

The 'Kiss You' boyband are releasing debut 3D flick This Is Us in August and the Morgan Spurlock-directed film will document the group's rise to fame since leaving the X Factor in 2010.

Speaking to MTV, producer Winston believes that One Direction's story is better than anything any script writer could come up with, saying:

"I think that if you were to go into a Hollywood office and say 'I got this idea for a film. Five unknown guys coming from absolutely nowhere and within two or three years there going to be some of the most famous artists on the planet, winning MTV Awards, be hugely successful, having world tours'...I think you'd go 'I don't believe that script. That can't be true. It could never happen'. Therefore the doc of what's happened to them over the last few years is more exciting than any script writer could ever write or come up with."

Winston added: "So, you've already got a wonderful story that you're able to tell. And Morgan and myself and all of the team have done a job of portraying that really and showing who the boys are, what they've gone through, both the ups and the downs, within that. And it shows them off as performers. We show them in all their glory [onstage], so if you haven't managed to get a ticket for some of their concerts you've got better than a front-row seat in the movie."
