Oh that is sad. What a loss: At least he made the most of his time and left his mark.
Also, I have a feeling that by the time Game of Thrones is through I'll probably be able to fill this thread with actors from it. Season 1 already got them off to a great start with Peter Dinklage as Tyrion, Harry Lloyd as Viserys, and Maisie Williams as Arya.
How could I have forgot this:
Kelly Bishop in the Gilmore Girls (plays the grandmother, Emily Gilmore).
Her lines were hilarious and she performed superbly.
