Yester year super heroine Radha’s daughter Karthika made her debut as heroine through the film Ko directed by K V Anand. After this film Karthika has not accepted any new films.
Radha while speaking about this said, " There are news that my younger daughter Thulasi is being introduced as heroine in Manirathnam’s film which has Karthik son in the lead role. There is nothing like that.
Every heroine will have the desire to act in Manirathnam’s film. If he had approached us, we would not have definitely refused. But nothing like that has happened. We would have ourselves mentioned that if anything like that has happened.

Many are asking me about the film in which Karthika is acting after Ko. She is getting lots of opportunities. We are listening to lots of scripts. Karthika is waiting for challenging. But so far she has not got such a kind of role."
