Hit singles, books, dolls and sold out concert tours ... it was only right that a movie would come next.
Mullingar teen Niall Horan (19) and his bandmates Liam, Zayn, Louis and Harry are set to make their Hollywood debut.
The One Direction lads will follow in the footsteps of Katie Perry and tween sensation Justin Bieber, who have already released 3D productions.
Bieber's film Never Say Never topped film charts around the world last year -- and 1D's film is expected to follow suit. The film will chart the band's rise to fame since they broke onto the scene after appearing on the UK version of the X Factor in 2010.
