"I've dubbed for Arya in Size Zero. It was so much fun. I closely follow Arya's work and it was an honour to dub for him," said Nandoo.
Directed by Prakash Kovelamudi, Anushka Shetty plays an obese woman and Arya as her husband and fitness trainer in the film.
For her role, Anushka nearly gained 20 kg and shed most of it through the course of the film.
The film also features Sonal Chauhan and Urvashi in important roles.
Size Zero, which has simultaneously shot in Tamil as Inji Iduppazhagi, is produced by PVP Cinema.
