Jayan, Avinash, Vivek, Raghuvaran, Kausalya and Karunas in supporting roles. Produced by Kavithalayaa Productions banner, filming began in October 2002 and was planned for a January 2003 release coinciding with the Thai Pongal festival, along with Vijay's other romantic comedy film Vaseegara. Eventually, the delays due to the replacement of some actors and actresses caused the movie to release in late 2003, coinciding with Diwali.
