I first saw her in NETWORK, and -- yes, I agree -- she was just consistently fine in every role I've seen in her since then. I truly admire actors of her ilk, providing rock solid support no matter the size of the part.
I was a callow 20-something during the half season run of HOT L BALTIMORE, and my standards of beauty had been pretty much defined by Hugh Hefner. Yet I found Conchata Ferrell's character very attractive. An awakening for my young self!
She had one of the more compelling story arcs on LA Law that has always stuck with me, it was where she was going to marry a guy from another country and then at the end finds out he was just marrying her for citizenship. Great stuff. RIP.
