I haven't gotten to the fifth season of AD either and unlike the hugely debated fourth season, almost nobody seems to TALK about that fifth season. I guess the movie won't be happening now either? Or was it ever?
She was in Clint Eastwood's Play Misty For Me, the first film he directed, where she tried to KILL CLINT. (He played a sensitive late night radio DJ, a hilarious piece of self-miscasting.)
Her best line on AD was the one where she confused "seaward" with "C-word," a joke I didn't even get like the first five times I watched the show.
