“He was a joy to work with,” Dietzen wrote. “Always had a smile. Always had something new to add to the page, and ALWAYS had the ability to steal every scene he was in! He had a quick and wry sense of humor and was generous with advice when I asked for it.”
He added, “The friendship and respect people saw between Ducky and Jimmy over the years mirrored the relationship we’d developed off camera. Whether it was going on field trips for character research, attending charity events or catching some golf together, he was always up for an adventure.”
