Longtime Star Trek director Mark Daniels, who directed 15 episodes of the original series, recalls in Captains’ Logs that A Private Little War, like many Trek outings, exceeded the limits of its budget. What is noteworthy is that he recalled the jacket incident very clearly, saying:
“I remember that episode also presented an issue regarding wardrobe. People on this planet were supposed to wear prehistoric clothes, and we discovered that it would cost a fortune to wear those clothes. Bill Theis, who has always been adept at dealing with such crises,” bought A set of cheap sheepskin jackets, we cut off the sleeves and turned them inside out. We were always trying to work around things like this because of budget constraints.”
Anyone with hippie parents — parents who were teenagers in the late 1960s — likely remembers seeing similar sheepskin jackets in their parents’ childhood closets. Lightweight sheepskin was a popular garment for young men in the late 1960s, and Bill Theis likely walked just a few blocks from the CBS Studios wardrobe building and bought a pile of them on any random afternoon. The final appearance of the asabi is earthy, primitive, and strangely convincing as the uniform of an agricultural community.
Naturally, actress Nancy Kovack, who played neurotherapist Nona, wore skintight pleated pants and a fuzzy tube top, leaving her stomach bare. This is old Roddenberry sexism at its most obvious.
