Watch One Direction thank fans for 'having their back' in new WWA concert film trailer

The short clip shows some of the band\'s biggest and most memorable concerts as they prepare to pack it all in to a handy film for us

It\'s happened, the moment you\'ve all (well, most of you) have been waiting for - a sneak peek at One Direction\'s upcoming concert film.

The film will follow the boys\' Where We Are worldwide tour as they perform in some of the biggest venues and soak up the explosive atmosphere.

And lets not forget the small matter of them performing all our favourite hits.

This short trailer shows the band backstage before stepping out to their adoring fans, and Niall says: "This is definitely the biggest tour we\'ve ever done, playing in stadiums all over the world."

Louis adds: "I think we\'re very lucky with our fans, that they take the pressure off us a bit. It kind of feels like they\'ve got you\'re backs."

The film will hit cinemas on October 11 and 12 - that\'s it, so understandably this sneak peek has got One Directioners a bit excited on Twitter.

Using the popular hashtag #1DWWAFilm, one user wrote: "We have your back boys #1DWAFilmTrailer #1DWWAFilm," while another added: "SO PROUD #1DWWAFilm #1DWWAFilmTrailer."

And a few have got really giddy about a final scene in the short trailer, which shows Liam throw his arm round Harry as they sing the final line - and yes, it\'s happened, they\'ve been nicknamed "Lirry."
