Karthika to act nude in art film?

she has signed a Malayalam art film ‘Makara Manju,’ which portraits famous painter Raja Ravi Varma’s works. She said, “I have agreed to this art film because, Lenin Rajendra who is very popular for making art films is directing this movie.”Famous Cinematographer Santosh Sivan is acting as Raja Ravi Varma in this film.

If, not mistaken Karthika has to act nude in some scenes, as the story demands for posing nude for making artistic portraits by famous painter Raja Ravi Varma. So far, Karthika is telling one and all that there would be no such scenes in the film and in case there are such scenes she will not act nude. But, when it is an art film that based upon the works of a artist who made several naked and semi naked portraits of women folk, how is she expecting the people to believe her that she is not going nude in that film?
