George Kennedy was in a Christmas episode of “The Young & The Restless” (as Victor Newman’s deceased father) either in 2010 or 2011, but what was notable was that aside from a snowy tv image, they didn’t actually show him, he only did voice-work for it (which was rather telling).
I didn’t feel him terribly effective as a villain on “Dallas”, anyhow, in the waning last seasons. I thought William Smithers, the actor who played the cold and asexual Jeremy Wendell, the Westar executive, was much better, creepier and menacing and he didn’t need the histrionics that so many folks playing villains seem to want to do.
Best wishes to George Kennedy.
I’m not the biggest Dallas fan...more of a casual observer.
