Lucasfilm and Star Wars: Force for Change today announced Roar For Change, a global challenge in support of UNICEF that invites fans to share their own version of Chewbacca’s fearsome roar on social media.

For each public post, like, or share on Facebook, Instagram, or Twitter that includes #RoarForChange between May 3 – 25, 2018, Star Wars: Force for Change U.S. will donate $1 to UNICEF USA, up to $1 million.

Funds will be used to support UNICEF’s lifesaving work for children around the world.  More details can be found at the official site.
