Sonakshi Sinha turns down Mani Ratnam's film

Mani Ratnam's upcoming bilingual has already created quite a buzz. 

After Aishwarya Rai Bachchan, who is making a comeback after a long maternity leave with this film, Shruti Haasan has also been signed. For the third heroine, the filmmaker had approached Sonakshi Sinha, but according to a source, the actress has refused the offer.

Ratnam met Shatrughan Sinha, who is a friend of the director, and outlined the role he had in mind for his daughter, before discussing it with Sonakshi. "She loved the role and it was really tough for her to let go of the offer. But she had prior commitments and didn't have the required dates. But she will definitely work with Mani Sir in the future."
