Dubai: Director Zoya Akhtar's feel-good drama Zindagi Na Milegi Dobara beat Shah Rukh Khan's sci-fi magnum opus Ra.One in this year's International Indian Film Academy Awards honouring technical excellence.

While Hrithik Roshan-starrer won five awards including Best Cinematography and Best Screenplay, Khan's super-hero production won four technical awards including Best Production Designer and Best Special Effects. Incidentally, these two films face stiff competition in the popular award categories too.

Vidya Balan's risqué drama The Dirty Picture also opened its account in the technical excellence category by taking home awards including the Best Dialogues and Best Costume Designing.

The winners will be decorated in the glittering ceremony that will be held in Singapore from June 7 to 9.
