Married People (1990)

The story involves three married couples in a New York City apartment building. Nick and Olivia Williams are a 60ish couple who owned the building and lease out the top two floors. Russell and Elizabeth Meyers live on the second floor in a non-traditional marriage (he is a writer who works at home; she is a high-powered lawyer); and Allen and Cindy Campbell on the third floor (he is a college student and she works as a waitress to put him through school).
