BarBara Luna (born March 2, 1939) is a vibrant and versatile American actress, dancer, and singer who, after a long career on Broadway and in film, became a science-fiction icon with her unforgettable guest-starring role as Lieutenant Marlena Moreau in the classic Star Trek episode, “Mirror, Mirror.”
A true child of show business, Luna made her Broadway debut at a young age, appearing in the original production of Rodgers and Hammerstein’s South Pacific. Her exotic beauty and talent led to a prolific film career, where she had memorable roles in the Spencer Tracy adventure The Devil at 4 O’Clock (1961), the adventure epic Five Weeks in a Balloon (1962), and the all-star drama Ship of Fools (1965).
Her role in the mirror universe episode of Star Trek as the “captain’s woman” who helps Captain Kirk survive in a hostile parallel dimension made her a legend among fans of the series. She has embraced this legacy, becoming a popular guest at Star Trek conventions for decades and even reprising her role in the fan-created series Star Trek: New Voyages.
