Bob Newhart said in a statement , " He was called ' The Merchant of Venom , ' but in truth , he was one of the kindest , caring and most sensitive human beings we have ever known . We are devastated , and our world will never be the same . We were totally unprepared for this . " Martin Scorsese , who directed him in '' Casino '' in 1995 , stated : " Don Rickles was a giant , a legend … and I can hear his voice now , skewering me for being so lofty . I had the honor of working with him on my picture '' Casino '' . He was a professional . He kept me doubled over with laughter every day on the set — yet he was a complete pro . " The Academy Awards honored Don Rickles in the 90th edition In Memoriam segment . '' Toy Story 4 '' was dedicated to him as well as animator Adam Burke
