I don't know. What do you want to do?
While he was a character actor for most of his career, he was a consumate actor. Look at his body of work
http://www.imdb.com/name/nm0000308/ and show me another actor with both the depth and breadth of Ernie. If you want to roll on the floor uncontrollably, look up some of the Johnny Carson Roasts - he quietly slipped in zingers when nobody was expecting them.
We are slowly but surely losing those who went from WWII to the various acting schools and then onto the stage. I am convinced that the experience of war had a special influence on the character of actors and their work at least equal to the influence of sound and color in films.
Who do we have replacing these folks?
stay safe.
