Robin Williams was not only a costar to Sarah Michelle Gellar in the CBS comedy The Crazy Ones – he was the dad she “always dreamed of having.”
In a statement to PEOPLE, Gellar reflects on Williams, who died of suicide Monday at the age of 63, and the indelible mark he made on her and her family. Gellar played the straightlaced daughter Sydney to Williams’ eccentric ad man Simon in the CBS comedy that was cancelled in May after only one season.
“My life is a better place because I knew Robin Williams,” Gellar said. “To my children he was Uncle Robin, to everyone he worked with, he was the best boss anyone had ever known, and to me he was not just an inspiration but he was the Father I had always dreamed of having. There are not enough adjectives to describe the light he was, to anyone that ever had the pleasure to meet him. I will miss him everyday, but I know the memory of him will live on. And to his family, I thank them for letting us know him and seeing the joy they brought him. Us crazy ones love you.”
