Notified of Sidney's passing, former DGA presidents commented on their memories of him:
"I know that I just wanted to move into his studio at his home, and keep looking at all the pictures he'd taken, and just listen to all of his fascinating stories about old Hollywood. I think he had far and away more stories and pictures than many of the research centers. I don't know anybody who dedicated more. I'll miss him even making fun of me."
"The thing about George is the Guild was his life. We owe him a great deal."
"He was very open, and that's what I was trying to be when I was president. To me that was one of the most important things that I was able to do, because people felt comfortable calling and talking to me. I think I got that from him."
"George's death left a void in the Directors Guild. He was a man for all seasons, a good friend, and he will be sorely missed."
"The Guild owes him a great debt for all the years that he was actively engaged in working for us, and for the amazing never-to-be-broken record number of years he served as our president. I was exhausted by four years in that job. Mr. Sidney served 14 years. Thank you, George."
"George Sidney will be greatly missed by all of us who came after him and had the benefit of all he accomplished for the Guild."
"George Sidney's distinguished career as a director, along with his years of service and dedication to the DGA, were an inspiration to us all. He will be greatly missed."
