Rajinikanth's two daughters - Aishwaryaa and Soundarya are in race to release the Hindi version of their respective films 3 (starring Dhanush) and Kochadaiyaan (starring Rajinikanth) around the same time, reports Subhash K Jha for Mid Day.Soundarya's Kochadaiyaan, featuring Rajnikanth was supposed to be dubbed in Hindi from Tamil. Aishwaryaa too has now decided to dub her film 3 in Hindi to cash in on the popularity of Kolaveri Di. Both Tamil and Hindi version of the film would hit the theatres simultaneously, says the tabloid."Yes, I am planning to dub 3 in Hindi and release it along with the Tamil version. It's a thriller; there's nothing culture-specific about it," confirms Dhanush to the tabloid."Everyone connected with the project felt that a Hindi version of 3 was the need of the hour especially with its track Kolaveri Di busting charts across the world. Then the way the song was shot, it sounded even better than expected. Only Dhanush had misgivings. He felt his Bollywood debut should not be a dubbed Tamil film. But he was outvoted by the rest of the 3 team," a source told the paper.Considering the fact that some important sequences of Kochadaiyaan still remain to be shot, theatres might see Dhanush's 3 first.Why this rivalry, rivalry Di!
