Earning a big break in Hollywood almost always involves mentoring or support from someone who is already established. In the case of Janet Waldo, it came in the form of actor-singer Bing Crosby, who invited her out to California after she won a talent contest he had sponsored. A large part of Waldo's career has been voiceover work, beginning with Cecil B. DeMille's "Lux Radio Theater" and continuing on to the 1960s TV series "The Jetsons," for which she embodied the role of Judy. On the radio, she was also, for eight years, Corliss Archer, the bubbly teenage star of the CBS series "Meet Corliss Archer." In a reminder of the way Hollywood also works, then and now, she was bypassed in favor of Shirley Temple for the feature film spinoffs. By the time Waldo wrapped things up and retired at the turn of the new millennium, she had added a whole range of voice work credits to her long, illustrious career in that field. They include Mrs. Slaghoople in "The Flintstones," Mrs. Tobbis in "King of the Hill," various voices for "The Chipmunks," and Shanna the She-Devil on "Spider-Man and His Amazing Friends."
