His dramatic acting in "Good Will Hunting".
Loved the line in Mrs. Doubtfire, when his wife asked Doubtfire, about her husband and learn her husband was killed by drink.
Sally Field asked, :was he was an alcoholic?
No, he was run over by a Guinness Ale truck.
I am sad to see such a wonderful caring person leave us.
RIP - Robin
