"Glad to inform, got the Theaterical trailer of Kochadaiiyaan censored today ( U-certificate) in Tamil&Hindi. Vikaramasimha censored in Telugu," Rajinikanth's younger daughter tweeted.

On Friday, Soundarya released the "Karbonn Kochadaiiyaan Signature Phone Series" at an event held in Chennai. Speaking to reporters at the event, Soundarya gave out some interesting tidbits about her father and her directorial debut flick. In response to a question on 'directing' her father, Soundarya revealed that her father was feeling awkward while shooting romantic scenes with Deepika Padukone. She also said that she would love to work with him once again, if given an opportunity.

The "Kochadaiiyaan" director also shared some details about her first film. Soundarya revealed that the legendardy actor Nagesh, who passed away in 2009, has been resurrected to a role. The film's team has got somebody to imitate the thespian's body language and those movements have been captured on computer and translated into a life-like manner on screen.

Speaking about the delay in the films' release, Soundarya said, "Films like Kochadaiiyaan will take 5-6 years for its making. Like how Avatar was in the making for 5-6 years because of the post production works which gobble up a large amount of time. That's the reason why we couldn't release Kochadaiiyaan as promised earlier," according to Cinemalead.

In a shocking revelation, the young director said that "Kochadaiiyaan" release date is not fixed yet. Earlier, Kochadaiiyaan's press release confirmed the film's release date as 11 April. Now, Soundarya's announcement has surprised the industry, as many screens have planned it for 11 April.

"Kochadaiiyaan," touted to be an historical drama, is one of the most-awaited films of 2014. The Rajini starrer is said to be the first Indian film to have used motion-capturing techniques.The film, made on a big budget over ₹100 crore, is jointly produced by Eros International and Media One Global Entertainment.
