Writer and former actress Twinkle Khanna, who has turned producer with "Pad Man", says she is proud of being associated with a movie that brings the spotlight on a "shamed" subject like menstruation.The shoot of the film -- inspired by Arunachalam Muruganantham who found a way to make cheap, affordable sanitary napkins for women in his village -- got underway last week in Indore.Talking about it, Twinkle said at an event here on Tuesday: "It (shoot) is going very well. Mr Muruganantham was also there. It's a wonderful project. It will bring awareness about something which has so far been cloaked and shamed, and I am very happy to be a part of the film."The movie features Twinkle's husband and actor Akshay Kumar in the lead role, with Radhika Apte featuring as his wife. It is being directed by R. Balakrishnan, better known as R. Balki.Twinkle spoke on the sidelines of L'Oreal Professional's launch of French Browns, the colour trend of 2017.
