Though the film has a sizeable sleaze content - Razdan made the controversial "Girlfriend" - and Vastavikta exposes quite a bit, she says she won't do a dare-bare act to add shock value to a film.
"Each artiste has to decide on their own and I will not expose to add shock value to a film. In case I accept any such role, it will depend upon many factors," says the daughter of the actor who gave Indian cinema classics like "Naya Daur" and "Neel Kamal".
Vastavikta says she didn't feel uncomfortable working with the director, who is more famous for making films with plenty of sleaze and sex.
"I was very comfortable with him and there was a family atmosphere on the sets. Karan Razdan never imposed his decisions on anybody. He was open to suggestions," Vastavikta told.
When asked her about her role, she said: "I am playing Kamini who is born and brought up in London. She loses her parents at a very tender age and is emotionally disturbed. I can't reveal more but something unusual happens in her life that changes everything."
Vastavikta has always aspired to be an actress. After finishing her degree course from New York, she took acting lessons under Vidur Sir and attended workshops with Satyadev Dubey and Shernaz Patel.
She also learnt jazz under Shiamak Davar and went to Terrence Lewis classes.
Apart from "Eight Shani", Vastavikta has three more projects in her kitty.
Her elder brother Puru Rajkumar is still struggling to make it big and so the family have pinned all their hopes on her.
