R Balki says he never wanted to make a biopic but he decided to go ahead with Padman as it gave him a chance to address an important issue like menstruation through the fascinating life story of Arunachalam Muruganantham. The director is best known for his films such as "Cheeni Kum", "Paa", "Shamitabh" and "Ki and Ka". "Padman", featuring Akshay Kumar in the lead, is a fictionalised account of Tamil Nadu-based Muruganantham, who created affordable sanitary napkins for the women of his village.
