Superstar's Kochadaiyaaan which was initially scheduled for release on Pongal alongside Jilla and Veeram has now been officially postponed. Originally spelled as Kochadaiyaan, the film was renamed (with an extra "i") for numerological reasons, There is also a buzz that another villain character of Superstar is being added to the movie to make it even more interesting and hence the delay.
