MUMBAI: Singers Shaan and Sunidhi Chauhan will be voicing for the lead characters Blu and Jewel respectively in Fox Star Studios’ forthcoming 3D animation film, RIO.

The duo will also be lending their voice for some of the Hindi songs of the film’s soundtrack.

Shaan says, “Associating with RIO was a very unique & exciting opportunity that I couldn’t refuse. The film is super fun and will be enjoyed by people of all ages. I had a great time dubbing and singing for the film.”

Chauhan said, “I wanted to do an animation film for years. Rio is such an amazing film that I just had to do it. Even though my character is a bird, Rio is a beautiful love story!”

Fox has also recently already roped in comical duo Ranvir Shorey and Vinay Pathak to do the Hindi voice overs for Nico and Pedro (Blu’s friends) respectively.

Jesse Eisenberg will be voicing Blu in the original version of the film; whereas Anne Hathaway lends her voice for Jewel.

RIO is a comedy-adventure which centers on Blu, a rare macaw who thinks he is the last of his kind. When Blu discovers there’s another – and that she’s a she – he leaves the comforts of his cage in small town Minnesota and heads to Rio.

RIO will hit theatres in India on 8 April, 2011, in English and Hindi.
