Jason Kempin/Getty ImagesAlmost all of us have been fortunate enough to see Robin Williams' talents unfold onscreen, but only a select group of people got to experience the magic of working with him.
The late actor's co-stars are understandably heartbroken about his tragic death. Sally Field, who acted opposite Williams in 1993's Mrs. Doubtfire, said in a statement she was "stunned and so sad about Robin," adding, "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, " added Fields. "There will not be another. Please God, let him now rest in peace."
Minnie Driver, who worked with Williams in 1997's Good Will Hunting, took to Twitter to express her grief. "My Heart's broken," she wrote. "Robin was a beautiful, kind soul. Can't bear that he's gone. So incredibly sorry for his family."
John Krasinski, who co-starred with Williams in 2007's License to Wed, tweeted, "To the kindest hearted man. Robin, know you will always be remembered by smiles, laughter and love. Thank you. Thank you. Thank you."
Mandy Moore, who played Krasinski's love interest in License to Wed, tweeted that she was, "Honored to have worked w such a bright light and brilliant man. Love and prayers to his family and friends. #RIPRobinWilliams"
Williams' Night at the Museum co-star Ricky Gervais was "deeply saddened" by the actor's tragic death, tweeting, "He was a lovely man who would keep everyone laughing even if he wasn't feeling good himself."
More co-stars and celeb pals weighed in with heavy hearts, too, like Chevy Chase, who said in a statement: "Robin and I were great friends, suffering from the same little-known disease: depression. I never could have expected this ending to his life, and to ours with him. God bless him and God bless us all for his LIFE! I cannot believe this. I am overwhelmed with grief. What a wonderful man/boy and what a tremendous talent in the most important art of any time–comedy! I loved him."
Robin Williams made the world a little bit better. RIP.
