Twin Peaks
She is best known for playing Sylvia Horne in Twin Peaks, appearing in the hit cult original 1990 series on ABC. She was in four significant episodes, including the very first one, the Pilot, and the then final episode, both key episodes directed by David Lynch.

She was also due to appear in the 1992 movie, Twin Peaks: Fire Walk With Me, with her character appearing in the original script, but did not as Richard Beymer - who played her character's husband, Benjamin Horne - and Sherilyn Fenn - who portrayed her on-screen daughter, Audrey Horne - chose not to return and the scenes featuring the Horne Family were written out. Many databases add the movie to her list of roles as "scenes deleted", but she didn't film any.
