One Direction's 3D movie will be about their fans.

The boy band - Niall Horan, Harry Styles, Liam Payne, Zayn Malik and Louis Tomlinson - recently announced they will make their big screen debut in August 2013 and their creator Simon Cowell is excited about what director Morgan Spurlock has planned.

He told MTV News: ''Well, I mean, for anyone whose fan of the band you're gonna get a chance to really see what it's like preparing for one of these big concert tours, a lot of it is about the fans.

''Morgan Spurlock's directing. He's cool, I met him. I think it's going to be amazing.

''He was just such fan of doing it. What he gets is storytelling and he likes detail and he's fun and the band likes him. I think he's going to make an interesting movie.''

Morgan recently spoke of his delight at working with the band, who found fame on Britain's 'X Factor'.

He said: ''This is an incredible opportunity and an amazing moment in time for the band.

''To capture this journey and share it with audiences around the world will be an epic undertaking that I am proud to be a part of.''
