Superstar Rajinikanth's 'Kochadaiyaan' is taking shape as a real big multi-starrer. Just days after roping in Katrina Kaif and Shobana, director Soundarya Ashwin has brought on board two popular personalities of Tamil cinema- Sarath Kumar and Nasser.

While Nasser already has the experience of sharing the screen space with the Superstar in some of his movies, including the blockbuster 'Chandramukhi', this is first time for Sarath to act with Rajini. And Soundarya is happy about making this star cast a reality.

"We are happy to have Sarath and Nasser sir in the team. The script demanded the presence of both. And they happily agreed to be part of the film when we approached them. Work is on in a fast pace and the shooting will start very soon," she says.

Buzz is that K S Ravikumar, who has penned the story, screenplay and dialogues for 'Kochadaiyaan', convinced Sarath to play a crucial role in the Rajini starrer. Ravikumar shares a great rapport with Sarath, as they have worked together in films including 'Nattamai', 'Natpukkaga' and 'Jaggubhai'.
