Star Trek: Elaan of Troyius

"Elaan of Troyius" is a third season episode of the American science fiction television series, Star Trek, and was broadcast December 20, 1968. It is episode #68, production #57, and was written and directed by John Meredyth Lucas, the only person in Star Trek production history ever to both write and direct a filmed Star Trek television episode, whether animated or live-action. In the episode, the USS Enterprise ferries a spoiled Elasian princess whose betrothal to a Troyian royal is hoped will bring peace to a star system at war. The episode's title character pays tribute to Helen of Troy from Homer's Iliad, and its plot borrows from William Shakespeare's comedy, The Taming of the Shrew.
