Movies and some off-Broadway, especially earlier in her career. Not much TV, although she had accepted a role in a major long running Fox series shortly before he died. In fact, she died the night before her first day on the set. I’d give the year of death, but that would make the research too easy.

EDIT: Also, according to Wiccapedia, she had a music career with some tunes charting. Club stuff.
