One Direction are recruiting fans to take part in their upcoming concert movie.

The boy band - Niall Horan, Zayn Malik, Liam Payne, Harry Styles and Louis Tomlinson - have posted a message on their website asking their followers to upload YouTube videos about their best 1D experiences.

Some of the stories will feature in their upcoming 3D movie, which is due to be released next summer.

Harry said: "We're always amazed by your stories and we're looking for some One Direction fans to be in our new 3D movie."

Zayn explained that the tales could be about something "crazy you've done to prove you're our biggest fan".

One Direction's film is being directed by Morgan Spurlock.
