NEW DELHI July 29: Filmmaker Shekhar Kapur, who is making a film on water scarcity with Hrithik Roshan in the lead, feels one awareness about the issue can be spread through social networking websites.“We all have Twitter handles and Facebook accounts, so why not use it to spread awareness about common issue like water conservation? It is a very powerful medium. If Mahatma Gandhi would have had a Facebook account, then we would have got independence very early,” said the director of acclaimed films like Masoom, Mr.India and Bandit Queen. The 66-year-old was speaking at The Water Landscape, a panel discussion with reference to water scarcity, at the ongoing 12th Osian's Cinefan Film Festival that kicked off here Friday. (IANS)
