Big Stars, Big Giving: Edward Norton and Crowdrise

Editor's Note: In an American Morning original series, "Big Stars, Big Giving," CNN National Correspondent Alina Cho looks at celebrity philanthropy and how these big stars can make a big impact. Through one-on-one interviews with Nicole Kidman, Halle Berry, Edward Norton, Julianne Moore and Justin Bieber, she shares what causes have become their passions, and how you can get involved. The one-hour special debuts December 24th and airs again on December 25th.

Edward Norton is a longtime advocate for various causes, so much so that he is cited in this year's Barron’s "Top 25 Givers" alongside Bill and Melinda Gates – the ONLY celebrity on the list.

Norton's latest project is Crowdrise, what he calls the "Facebook of philanthropy." Crowdrise is an innovative new web platform that brings the fun of social networking to fundraising and volunteerism.

Like Foursquare, members can earn points and win prizes when they reach certain fundraising benchmarks. "We've created a fun and easy way for people to raise money for the causes they care about," Norton says. He is particularly interested in inspiring a new generation of givers.
