With the project slated to go on floors this year, actors Nayanthara and Sivakarthikeyan will come together for the first time for a yet-untitled Tamil project directed by Mohan Raja. A source said, “The makers were in talks with three heroines, with Nayanthara being the front-runner. Since she had previously worked with director Mohan Raja in 'Thani Oruvan', she jumped at the opportunity the moment she heard the script.” Rest of the cast and the crew are yet to be finalised.
