Matt Damon and Ben Affleck paid tribute to Robin Williams on Monday night by wearing San Francisco Giants hats, despite being Boston Red Sox fans. The duo was honored at the Revels & Revelations event in the Bay Area, organized by the mental health organization Bring Change to Mind, and received the Robin Williams Legacy of Laughter Award for their contributions and the power of storytelling.

When Damon and Affleck took the stage to accept the award, they donned Giants hats in honor of Williams, a long-time fan of the team. Damon jokingly said, "We had to finish this," as they both put on the hats and added, "For the first time in 55 years, and this is for Robin." The actors, who starred alongside Williams in Good Will Hunting in 1997, noted that Williams won the Academy Award for Best Supporting Actor for that film.

Damon shared with the crowd the process of making the film: "We were trying to get the movie made in our 20s, and Robin read it and said he would do it, and our problems were solved. The studio had a lot of notes, but when Robin said, 'No, the script is just that beautiful,' they said, 'We think so too!' and we went and made the movie."

In his acceptance speech, Affleck said, "This is a way for us to thank Robin. He had a more meaningful impact on our professional lives than anyone else could, and thanks to him, many of the things we dreamed of came true. Also, Good Will Hunting is about a young man dealing with mental health issues and finding someone he can talk to and trust. In that context, it's very fitting to honor him; don't you think Robin would be very happy and proud of this?"

Williams' children, Zak, Zelda, and Cody Williams, were present to present the award. Glenn Close, Sarah Silverman, Chase Stokes, and Chris Martin also attended the event. The night celebrated 15 years dedicated to starting conversations about mental health, raising $2.5 million in donations.
