Two filmmakers in India are caught up in a landmark censorship battle to show their movie after the country's censor board refused to certify it. Khushboo Ranka and Vinay Shukla have directed An Insignificant Man - a fly-on-the-wall documentary chronicling the spectacular rise of Arvind Kerjiwal from an activist to a controversial vigilante-politician. They were meant to be in New Zealand this week promoting the movie as part of this year's film festival, but are instead appealing the board's decision for them to cut parts of the documentary. At the heart of An Insignificant Man is the most polarising man in India today. Filmed over the course of two years, the film offers a unique insight into Arvind Kejriwal and the Common Man's Party - and their journey through the lanes of Delhi's shantytowns to the closed corridors of political power, in the largest democracy in the world.
