Series: Star Trek: The Original Series
Season 3, Episode 18
Original Air Date: January 31, 1969
The episode was co-written by Shari Lewis (puppeteer for Lamb Chop) and her husband Jeremy Tarcher. Lewis was a huge fan of the show and deliberately favored Scotty in this tale, feeling Captain Kirk was the one who always got the girl and it was high time someone else got a shot. Unfortunately for Scotty, "The Lights of Zetar" marks Mira's only appearance in the Star Trek universe. She does, at least, survive to the end of the episode.
In addition to designing the now iconic Starfleet uniforms, Theiss became well known for the Theiss Titillation Theory, the claim that "the degree to which a costume is considered sexy is directly proportional to how accident-prone it appears to be." This philosophy helps explain the rather daring/questionable/offensive (depending on one's point of view) choices frequently made for the costumes of Star Trek's female guest stars.
Theiss died of AIDS in 1992.
