Star Trek TOS - The alluring France Nuyen played the seductive princess whose tears have the power to make a slobbering love slave out of Captain Kirk - temporarily of course, because his only true love is the starship Enterprise. Duh.
France Nuyen was a popular actress throughout the 60's - frequently referred to as "an exotic beauty" because of her French/Vietnamese heritage - she co-starred in films like South Pacific, Diamond Head, Battle for the Planet of the Apes and The Joy Luck Club, and such TV shows as Gunsmoke, The Man From U.N.C.L.E., Hawaii Five-O, Kung Fu, and Charlie's Angels.
But what was really impressive about her was that, after a long career as an actress, she earned a master's degree in clinical psychology. She began a second career as a psychological counselor for abused women and children, and women in prison.
Not bad - changing the course of her life in her mid-forties and making an actual positive difference in the world.
Just do NOT let her tears get on you!
