Japanese actress Yoko Tani made several leading appearances in European and American films of the '50s and '60s. She could be seen as a Vietnamese in The Quiet American (1958), a Chinese in Marco Polo (1961), and a general hanger-on in the wake of womanizing Dean Martin in Who's Been Sleeping in My Bed? (1963). More attractive than talented, Yoko Tani had the distinction of starring in one of the few Communist-bloc science fiction films of the '60s. Ms. Tani appeared as medical doctor Sumiko Ogimura in the East German-Polish collaborative production First Spaceship on Venus (1962).
