[7] She also played the leading lady in the film serial Congo Bill[8] and worked for Warner Brothers briefly in 1950.

The studio had plans to mold Moore as its next film star, hoping she would bring Columbia the success that 20th Century-Fox was having with Marilyn Monroe.

She first gained attention as a doomed gun moll in Nicholas Ray's film noir On Dangerous Ground in 1952.

In 1954, she starred in The Other Woman, playing a B-movie bit player who strikes at her movie director for revenge when he declines the offer for her to be in his picture.

Upon completing a supporting role in Women's Prison (1955), Moore signed a brief deal with Universal Pictures to play a suicidal prostitute in the low-budget thriller Hold Back Tomorrow (1955), again opposite Agar.

During this period of 1950s Hollywood, Moore was one of several buxom blondes to achieve notability following Marilyn Monroe's major breakthrough; the others included Jayne Mansfield, Mamie Van Doren, Diana Dors, Sheree North, Anita Ekberg, Barbara Lang, Barbara Nichols, Joi Lansing, Carol Ohmart, Pat Sheehan, and Greta Thyssen.
