While working in small community theater productions, mostly in unsympathetic roles, she was discovered by a talent scout from RKO Pictures.

[3] One of her early roles was playing Raymond Burr's girlfriend in his first film, Code of the West.

[6] Forman became better known for her appearances in movie serials in which she differed from other actresses by playing villainesses exclusively.

In 1952, in the nostalgic musical comedy By the Light of the Silvery Moon starring Doris Day, Forman spoofed her serial persona by appearing briefly as an evil woman in a young boy's daydream.

She also made guest appearances on The Cisco Kid starring Duncan Renaldo and Leo Carrillo in the early 1950s.
