During this time, Anderson was known by her birthname of Judith Carr. She did not begin using the moniker "Juliet Anderson" until later in her adult film career, when she made the transition from 8mm productions to feature films. She has also used the stage names of Alice Rigby, Judy Callin, Ruby Sapphire, Judy Carr, Aunt Peg, Judy Fallbrook, and Judith Anderson.
After a further period overseas, Anderson returned to the United States during the early 1970s, and became involved in the pornography business while a student at San Francisco State University. She was working in advertising when she answered an ad by hardcore pornography producer Alex d’Renzy, who was looking for an actress. Cast in the movie Pretty Peaches, Juliet's career quickly took off from there. She acquired the name of "Aunt Peg" during a movie where she was portrayed as having sex with a niece, who cried out: "Oh, Aunt Peg!"; thus arose the moniker by which Anderson is best known to her fans. She appeared in several pornographic magazine pictorials during this timeframe, made appearances on radio and television, and operated a mail-order business, casting agency and a phone-sex service.
In 1984, Anderson chose to leave the adult film business due to differences between herself and producers regarding the editing of Educating Nina, a video she directed starring Nina Hartley. She moved to Northern California, where she ran a bed and breakfast for a time and opened a massage therapy office. Anderson chose to return to pornography in 1995, making new movies as an actress, producer and director.
By 2009, Anderson lived in Berkeley, California with four cats. She continued to work in the adult film industry, and had announced plans to produce new films. She also worked as a relationship counselor, giving private workshops for couples focusing on "Tender Loving Touch," in which sexual touching is seen as "play, not as foreplay." She contributed to the books The New Sexual Healers: Women of the Light and The Red Thread of Passion, and authored articles for magazines and newspapers.
