Ross had previously made an uncredited appearance in the classic 1957 film The Sweet Smell of Success, alongside Lawrence Dobkin and John Fiedler. In 1968, she appeared in an uncredited role of a savage Human in the classic science fiction film Planet of the Apes, which also featured James Daly, Lou Wagner, Paul Lambert, Billy Curtis, and Felix Silla, and a musical score by Jerry Goldsmith. Despite rumors to the contrary, "Jane Ross" was not a pseudonym used by Beatrice Arthur, and they were not the same person. [1](X)
