In 1984, while a freshman at Barnard College, Nixon made theatrical history by simultaneously appearing in two hit Broadway plays directed by Mike Nichols. They were The Real Thing, where she played the daughter of Jeremy Irons and Christine Baranski; and Hurlyburly, where she played a young woman who encounters sleazy Hollywood executives. The two theaters were just two blocks apart and Nixon's roles were both short, so she could run from one to the other. Onscreen, she played the role of Salieri's maid/spy, Lorl, in Amadeus (1984). In 1985, she appeared alongside Jeff Daniels in Lanford Wilson's Lemon Sky at Second Stage Theatre.
