One Direction are asking fans to upload YouTube videos about their best 1D experiences.
The band want to find super fans whose stories will feature in their upcoming 3D movie.
The video sees Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson ask their fans to tell them their best One Direction stories and reveal that some of the lucky ones will be chosen to appear in the 3D film about the band.
Malik explained that it could be stories about meeting other One Direction fans or "something crazy you've done to prove you're our biggest fan".
Fans have to submit a video to YouTube of them talking about their greatest 1D experience.
The film, to be released on August 30, 2013, will apparently be a 'behind-the-scenes' look at the boyband.
It is directed by Morgan Spurlock, who made 2004′s fast food documentary Super Size Me, and co-produced by Simon Cowell.
