New Delhi: Akshay Kumar is proud of his coming film "Pad Man" -- a film highlighting awareness on menstrual hygiene. The actor says he always wanted to support socially relevant cinema, but couldn't due to lack of funds.

The actor also added that there isn't a single commercial film on sanitary pads, not even in Hollywood, as people shy away from discussing the topic in public.

"I always wanted to work and make such films but I was not a producer during that time. I didn't have enough money, but now I can. My wife told me about Arunachalam Muruganantham and then we met R. Balki. So we thought about making this movie," Akshay said while promoting "Pad Man" here on Monday.

"Even Hollywood does not have a single film on sanitary pads or menstrual hygiene. People always make documentaries but they don't want to make commercial films because they want to shy away from the issue. We have tried to do that," he added.

Akshay's "Pad Man" -- which marks his wife Twinkle Khanna's maiden production venture -- tells the story of a real-life superhero who invented a low-cost sanitary pad manufacturing machine to bring a menstrual hygiene revolution for women.

The film is based on a short story from Twinkle's book "The Legend Of Lakshmi Prasad". The story is inspired from the life of Muruganantham, a Tamil Nadu-based social activist who revolutionised the concept of menstrual hygiene in rural India by creating the low-cost sanitary napkins machine.

Its unique story, inspiring message and Akshay's portrayal -- once again -- as a common man's hero, has kept the anticipation level high for the R. Balki directorial, which also features Sonam Kapoor and Radhika Apte.

While many people, including Bollywood stars, are hailing the film, there are some who are criticising Akshay for talking about the issue in the open.

Muruganantham, who was also a part of the press meet, expressed his views on the film made on his endeavour. He said, "I never thought a film will be made on my life and my work. When I used to say the word 'menstruation', people used to beat me up. Who would have thought that there would be a time when a film will be made on my life?"

The film is slated to open in India on Friday (9 February).
