Zabriskie is perhaps most familiar, however, for her television work. After appearing in a recurring role on the soap opera ''Santa Barbara'', she played a major role on the David Lynch series ''Twin Peaks'' and its spin-off film, ''Fire Walk With Me'' as Sarah Palmer, the eerily psychic mother of the doomed Laura Palmer. Zabriskie had previously appeared in Lynch's ''Wild at Heart'' — notably as the twin sister of a character played by Isabella Rossellini, an actress eleven years her junior. Zabriskie may also be remembered as the actress who portrayed the long-suffering Mrs. Ross, a recurring character on the sitcom ''Seinfeld''. In this series, Zabriskie again played the mother of a doomed woman — Susan Ross, George Costanza's fiancee, who dies from licking tainted envelopes. Zabriskie's character's husband on the show was played by her former ''Twin Peaks'' co-star Warren Frost.
Grace has at times worked in radio, collaborating with radio dramatist/monologist Joe Frank several times.
Zabriskie recently appeared in the American remake ''The Grudge'', in which she played a senile grandmother sensitive to the paranormal occurrences in her home. She also stars in ''Big Love'', an HBO drama series that seriously explores the issue of polygamy.
