The actress in this movie is "Akshata Rao" she has acted a few Kannada movies and that too only with Shankar nag. I think two movies only. There is no reference about her in the net.
I came to know about her on tracing the original source of Cheeni Kum song with was adapted from Tamil song Viyzile Mani Viyzile for the film Nooravadhu Naal staring Mohan and Nalini which in turn (song)adopted from Kannada film Greeta.
All the three songs were by Ilayaraja and first two were sung by SPB and S.Janaki and latest one by Sherya Goshal.
Kindly post more info on the actress Akshata Rao, if any body can kindly put is hosted.
The film also have another song which was also remade in Tamil for Karthick, Devadai Ilam Devi.
