I also liked him, albeit in a way perhaps noone else did.. in 'Backdraft' as the imprisoned arsonist.

Martin Mull passed away. He was 80, and it says he passed after battling a long illness. I thought he was hilarious, especially when he and Fred Willard were doing something together. They were friends for a long time, even before they appeared on Roseanne.
R.I.P. Mr. Mull
I'm wondering if Pauly Shore is still going to make a movie about him. It was amazing how much Shore looked like him, in the pictures I saw. My he rest in peace.
What a vibrant, good-natured soul. Rest in peace.
One day after celebrating his 76th birthday. Wow!
