Soundarya R Ashwin, who is making her directorial debut with 'Kochadaiyaan', which has her father Superstar Rajinikanth in the lead, is said to be working tirelessly towards one single agenda.

That is to release the movie on the Superstar's birthday on December 12, to make it as a perfect treat to millions of Rajini fans.

"The post production works are on in a hectic pace. Since the movie is being made using performance capturing technology, undivided attention is needed for event minute things," sources say.

It is expected that the audio launch function would take place soon. With A R Rahman scoring the music, the film has Deepika Padukone, Sarath Kumar, Jackie Shroff, Shobana, Nasser and Aadhi in crucial roles.
