National Award winning filmmaker Suman Ghosh plans to release his censorship controversy-mired documentary on Nobel laureate Amartya Sen online in a "couple of months" in its entirety, including four words that the Indian censor board has objected to.

The Argumentative Indian, originally scheduled for a July 14 release, was refused the green signal by the Indian censor board over the use of the words "cow", "Gujarat", "Hindu India" and "Hindutva", by Sen.

The hour-long documentary, structured as a free flowing conversation between Sen and his student and Cornell economics professor Kaushik Basu, has already been screened in New York and London. It had a special screening in Kolkata on July 10.

The Central Board of Film Certification (CBFC) officials in Kolkata verbally asked Ghosh to mute at least four words, including "cow" and "Gujarat", from Sen's interview in the film.

"I will release the film online. I have some screenings organised abroad so I can't release it before that. It will take a couple of months. It will be there in its entirety," Ghosh said.
