Srinagar, Aug 5 - Britain-based Indian filmmaker Jagmohan Mundhra is determined to go ahead with his pet project , a biopic on Congress president Sonia Gandhi, and has researched a lot on the subject. He says he wouldn't even mind if the Indian government decides to ban the film later, but make the film he will.

'When I decided to make a biopic on Sonia Gandhi, about facts and moments that nobody knows about..., I got a legal notice from the Congress party stating that you are making a film on Sonia Gandhi and you have not even taken permission from her.

'In my reply, I mentioned that I have bought the rights of a book by Rasheed Kidwai. After that whatever research I have done till date is from published material, all verifiable. She can sue me if I am factually wrong, but if I make a film on a public figure which is factually correct, then it is not wrong.

'I told them: let me make the film; if you don't like it then ban it,' Mundhra told IANS in an interview. He has made critically acclaimed films like 'Provoked' and 'Bawander'.

Mundhra, who has been trying to make the film for a few years, has finalised Italian actress Monica Ballucci for the lead.

The filmmaker said he has done extensive research for the film and is eagerly waiting for a go ahead from Sonia Gandhi. The United Progressive Alliance chairperson had asked him to contact her after the 2009 general elections.

'Whenever I take on a subject about real people, I don't treat it lightly. I do a lot of research, I do it properly so that there are no factual mistakes. But we have to take cinematic liberties in order to keep the pace of the film intact, but I don't want to commit any factual mistakes,' he said.

Mundhra said he didn't seek permission earlier from Sonia Gandhi for two reasons. 'I did not go to ask her earlier because I thought that if she says yes then the (political) opposition would have said that she is getting made a propaganda film.
