Description   [from Freebase]

Eileen Dietz (born January 11, 1945, Bayside, New York) is an American actress who is best known for her appearances in many horror films such as the face of the demon in The Exorcist and for her portrayal of characters on the soap operas Guiding Light and General Hospital. As a child, Dietz appeared in commercials with her twin sister Marianne, and beginning at the age of 12 she started studying acting at the Neighborhood Playhouse. She made her television debut in 1963 in a small guest role on The Doctors. Shortly thereafter she landed a recurring role on the soap opera Love of Life. She made her film debut starring in the 1966 movie Teenage Gang Debs as Ellie. The following year she portrayed Penny Wohl in the critically acclaimed independent film David Holzman's Diary. The film never got much in the way of theatrical distribution despite having Dietz's nude scene featured in Life Magazine's photo spread and in the book of the film. She didn't recall if she auditioned for the role of Penny but she added, "it was a fun shoot." Dietz spent much of the late 1960s and early 1970s appearing in theatre productions.
