A first trailer for One Direction's behind-the-scenes 3D documentary film has hit the net.
The trailer of the doco, helmed by Super Size Me director Morgan Spurlock, shows a lot of screaming teens, the boys' mums and of course Niall Horan, Louis Tomlinson, Harry Styles, Zayn Malik and Liam Payne goofing around as they promote their hit album Up All Night..
The film, to be released in New Zealand on September 19, follows similar behind-the-scenes documentaries by pop stars Justin Bieber and Katy Perry. Bieber's Never Say Never (2011) grossed some US$73 million at North American box offices.
One Direction rose to fame on the British version of Simon Cowell's talent show The X Factor in 2010 and have gone on to be one of the biggest pop sensations worldwide in recent years.
