India, July 21 -- Actor Malavika Mohanan has been tirelessly working to educate children from tribal communities in Kerala. The 27-year-old says: "Many years back, I had shot for a film in Wayanad (Kerala) which never got released. But I ended up spending time with the tribal communities in the area. I was starting out and didn't have the financial means to help them. Some of the children didn't get to have even one square meal a day," she says....
