Despite being awarded an A-certificate, "Mardaani", which earned Rs.15 crore in the opening weekend, has been made tax free in Uttar Pradesh and Madhya Pradesh.
The actress is keen to show the film on female trafficking to children who are above 12 years.
"I am so happy with the response to 'Mardaani'. Many people have asked me why the film has been given an A-certificate? I am going to put in all my effort to re-certify 'Mardaani', which will make a huge difference," Rani told reporters here.
The actress wonders what the censor board is trying to protect the young viewers from?
"...this is very sad and disappointing. So many people have called me and said it's so sad that they can't show the film to their children and that they are waiting for the film's DVDs so that their children can also watch it," she said.
Rani campaigns for a new category that allows children above 12 years to watch a film like "Mardaani", which has been directed by Pradeep Sarkar and produced by Yash Raj Films.
She said: "I have people from NGOs who want to show the film to the children. So I will take a letter from them to the censor board. We have made the film for kids to spread awareness.
"I don't know why we are shying away from reality. Had we wanted a U/A certificate, we could have easily got that by chopping a few scenes, but that's not the point. We want 12 years and above kids to watch the film."
Meanwhile Rani urged the Maharashtra government to make "Mardaani" tax free.
She said: "I am so happy that the film has been made tax free in UP (Uttar Pradesh) today and that shows the relevance of the film. I also want Maharashtra government to make it tax free."
