Matt Damon: “Robin brought so much joy into my life and I will carry that joy with me forever. He was such a beautiful man. I was lucky to know him and I will never, ever forget him. I truly hope the people in the media can find it within themselves to give his family some privacy during this horrible time.”
Louie C.K.: "Goodbye pal. Thanks for everything."
Danny DeVito: "So sad to think about this. Hard to speak. Hard to say. Hard to take. All I can think about is what a joy he was to be with. I’m devastated. I'm sending my love to his family and everyone who loved him. My heart is broken by this news."
Albert Brooks: "Shocked by the news of Robin Williams passing. Rest in peace my friend."

Sally Field: "I feel stunned and so sad about Robin. I'm sad for the world of comedy. And so very sad for his family. And I'm sad for Robin. He always lit up when he was able to make people laugh, and he made them laugh his whole life long.... tirelessly. He was one of a kind. There will not be another. Please God, let him now rest in peace."
Jessica Chastain: "Robin Williams changed my life. He was a great actor and a generous person. Through a scholarship, he made it possible for me to graduate college. His generous spirit will forever inspire me to support others as he supported me. He will forever be missed."

What a wonderful man/boy and what a tremendous talent in the most important art of any time -- comedy! I loved him."

The producers of "The Crazy Ones" also released a statement: “Robin Williams was a comedy giant, and although we only knew him personally for a season, he was warm, funny and a true professional. His cast and crew both loved him and loved working with him, and our hearts go out to his family and friends. He was one of a kind.”
President Barack Obama also remembered the funnyman: "Robin Williams was an airman, a doctor, a genie, a nanny, a president, a professor, a bangarang Peter Pan, and everything in between. But he was one of a kind. He arrived in our lives as an alien -- but he ended up touching every element of the human spirit. He made us laugh. He made us cry. He gave his immeasurable talent freely and generously to those who needed it most -- from our troops stationed abroad to the marginalized on our own streets. The Obama family offers our condolences to Robin’s family, his friends, and everyone who found their voice and their verse thanks to Robin Williams."
Williams' "Night at the Museum" co-star Ben Stiller shared a wonderful story: "I met Robin when I was 13 at The Improv. I was there with my parents who were performing and it was crowded and I heard this voice behind me saying 'Stay close to your mother you'll be safe! Stay close to your mother you'll be safe!' I turned around and it was Robin. For a 13-year-old who was a huge 'Mork and Mindy' fan it was sort of like the end of the world. I never forgot it. So working with him years later I always had this little voice insides of me going 'you are acting with Robin Williams! This is the coolest thing ever!' I never got over being a fan. I think most people my age have the same feeling -- that he and Steve Martin and Bill Murray sort of represented what it meant to be funny.
"His kindness and generosity is what I think of. How kind he was to anyone who wanted to connect with him. And he could not help but be funny all the time. He would do something as long as it would keep you laughing. He made many, many film crews laugh out loud before the audiences ever saw it. He made such a big impact on the world. So there is the man, and his talent, and I think in his case both were extraordinary."
