One Direction: The Movie

'What Makes You Beautiful' stars One Direction are making a TV movie with Simon Cowell and James Corden.

The X Factor boss Simon Cowell coughed up £150,000 for the lads' film and Gavin And Stacey star James Corden, who has his own production company, is helping to make the show.

"We have been following the lads ever since they first embarked on their plans for pop world domination," a film insider said.

"The cameras follow them to the US where they worked on their first album and got into all sorts of mischief."

The movie will be shown on ITV2, and will reveal all on what really goes on behind closed doors for Harry, Liam, Louis, Niall and Zayn.

"The lads are pretty candid," the source revealed to The Sun.

"We're sure it will be a hit among their army of fans."

One Direction's Vodafone Big Top 40 No. 1 'What Makes You Beautiful' is out to buy and download now. The release date of the TV film has yet to be announced.
