Connie Nielsen hates waste. In 2010 she went to the slums of Nairobi to shoot the film Lost in Africa and decided to help out. “I was going to give $50,000 for a well, but I heard that it wouldn’t last more than a year,” says the Danish actress, who is now costarring in the new TV political drama Boss. “I’m tight [with my money], so I said, ‘No way.’ ” Instead, Nielsen undertook a bigger cause: Revamping the infrastructure of Kibera, Africa, with Human Needs Project, a community-based rehabilitation program for providing water and power to people in need. In the past year, she has visited Kibera and Kenya three times and set up a scholarship fund (Road to Freedom Scholarships) for 17 local girls to attend boarding schools. Apparently, a little frugality can go a long way. Here is a journal of Nielsen’s six-day September visit to Kibera.
