After graduating from university with a degree in philosophy, Katharine Houghton was helped into the world of acting by her aunt, legendary actress Katharine Hepburn. She had her first on-screen appearance in the TV anthology series "ABC Stage 67." Her next performance was her first and best known film role, playing a young woman who brings her black fiancé home to meet her parents, appearing alongside her famous aunt, who was playing her mother, in the 1967 romantic drama "Guess Who's Coming to Dinner." At the same time, Houghton was developing a strong theater career, eventually going on to appear in over 60 stage productions. In 1975, she had a starring role in the poorly- received horror film "Garden of Death." Following that role, she had a few more TV appearances, such as in the historical dramatic mini-series "The Adams Chronicles" in 1976, and in the 1987 mini-series "I'll Take Manhattan," but after these, she concentrated on her film and stage career. Some of her later films include the 1991 gangster movie "Billy Bathgate," the 2004 biographical drama "Kinsey," and 2010's family-adventure "The Last Airbender," which was directed by M. Night Shyamalan. Along with her acting career, Houghton is a celebrated playwright, who has seen eleven of her plays go into production.
