Ben Affleck and Matt Damon are set to receive the 9th Robin Williams Legacy of Laughter Award at the nonprofit, Bring Change to Mind, in San Francisco. The event will be held at the Fort Mason Center for Arts & Culture on April 27. The award is designed to recognize their impact on storytelling and connection to spark real change. The ceremony will also be attended by Robin's children, Zak, Zelda and Cody Williams. The charity's Revels & Revelations Celebration is a "powerful night of storytelling, celebration and impact" and celebrates 15 years of impact and a decade steering student programming.
