Aishwarya Dhanush, elder daughter of superstar Rajanikanth is currently working for Karthi starrer 'Aayirathil Oruvan'. She said that the movie is rewarding her an altogether different experience after her experience as an associate director in her dad's film Baba." In my first movie, all i did was to observe the director to observe the nuances. The second movie involved a lot of work. Director Selvaraghavan is a taskmaster. It is both challenging and a learning experience" , she said.
