A few days back we had reported that after the success of 'Devi', Prabhu Deva will be acting in another film which has been titled as 'Yung Mung Sung'.

The film touted to be a comedy entertainer dealing with martial arts, will be directed by Arjun, a former associate of directors Ram of 'Mundasupatti' fame and Ravikumar of 'Indru Netru Nalai' fame. Catherine Tresa is likely to play the female lead in this film.

Now the latest addition to the star cast of 'Yung Mung Sung' is the much sought after comedian and supporting actor RJ Balaji.

This will be Balaji's second film with Prabhu Deva as he was also part of 'Devi'.

RJ Balaji has been going places as a comedy based supporting actor. He is presently part of director Mani Ratnam's 'Kaatru Veliyidai', A.R.Murugadoss's Tamil-Telugu bilingual with Mahesh Babu in the lead role and Mohan Raja's untitled film with Sivakarthikeyan.
