Before becoming a star, Mary worked as a booking agent for an airline, a hat-check and cigarette girl at the Roosevelt Hotel, and as a photojournalist.
At the age of nine, Mary was chosen by Count Basie's Orchestra to perform with them for two shows. Together they performed the song "Little Girl Blue."
Mary's record at the Daytime Emmy Awards is as follows:
- 1977 Nominee; Outstanding Actress
- 1976 Nominee; Outstanding Actress
- 1974 Nominee; Best Actress
All were for her work on Search For Tomorrow.
Mary: I only stayed in Hollywood for three years. Being a starlet wasn't my thing. There's a lot of hanging around pools. Starlets always drape themselves around somebody's swimming pool. I never remembered to shave my legs or I was sunburned or something.
