[Note: the following comes after a prolonged discussion on Roddenberry's affairs during the production of Star Trek.]
The discussion of Gene Roddenberry's sexual attitudes and adventures may seem out of place when analyzing the development of Star Trek -- but it's actually a very important component of Roddenberry's vision of the future. If he had not been the one exercising creative authority, the overall face of the show would have been vastly different. Nowhere was this more evident than with his treatment the women of Star Trek.
HERB [Solow]: Gene continually tended to "his" women: regulars, guest stars, and extras. Obsessively involved in their costumes, their hairstyles, their makeup -- even their footwear -- he created a look best described as "available sexuality." Their costumes were as scant as possible, designed for the maximum display of breasts and legs. Yes, actresses were chosen for their acting talent, but voluptuous lips and seductive eyes were very important to him. And in most instances, the characters they portrayed were emotionally subordinate to the men of Star Trek. Women were, essentially, sex objects always ready for action. And they were the antithesis of the actresses staring in other dramatic television series of that era: Barbara Bain [Mission: Impossible], Amanda Blake [Gunsmoke], Barbara Anderson [Ironside], Stephanie Power [The Girl From U.N.C.L.E.], and of course Barbara Stanwyck [Big Valley], all playing characters of substantial independence and distinction.
Everyone had a role in Gene's future world. And for Gene, a woman's role was primarily as a decorative tool in a man's workshop.
