Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson may make up the biggest boyband in the world, but they are eager to prove that they're just a normal bunch of lads in their new documentary movie. The film sees them going back to their roots and reuniting with old friends; Harry goes back to the bakery he used to work at, while Zayn shows he hasn't forgotten his loved ones by buying his mum a luxury house of her own. We see them through the eyes of their fans across the world, their proud parents and the owner of their record label Simon Cowell. They reveal how they've always wanted to sing, and show their genuine brotherly bond through countless on and off tour shenanigans including fishing and camping trips.

'One Direction: This Is Us' has been directed and produced by the Oscar nominated Morgan Spurlock ('Super Size Me', 'Where in the World Is Osama Bin Laden?') alongside Simon Cowell, Adam Milano and Ben Winston. It follows in the same ilk as fellow teen star Justin with his movie 'Justin Bieber: Never Say Never' in 2011 and Katy Perry's 2012 flick 'Katy Perry: Part of Me' and is set to be released in cinemas on August 30th 2013.
