Her professional debut was in the live television drama Can You Coffeepot on Skates?, presented in 1956. This was followed by television appearances on Matinee Theatre and Alfred Hitchcock Presents and her cinematic debut in Sweet Smell of Success. On October 19, 1957, she opened on Broadway at the Bijou Theater, playing "the Girl" in William Saroyan's new play The Cave Dwellers to uniformly good reviews.[5][6][7] The following year she was in the Playhouse 90 production of In Lonely Expectation, which brought her to the attention of Rod Serling and led to her role as the ballerina in the iconic Twilight Zone episode. She had several later television and stage roles, most notably in an episode of the television show Bonanza, "Dark Star" in the first season, episode 31 (1960). In 1960 she played Ruby, the female lead, in the little-seen film Key Witness with Jeffrey Hunter and Dennis Hopper.
