Duplex (2003)

In terms of living the American Dream, Alex and Nancy have it pretty good. They are a young, vibrant couple in New York City with bright futures ahead of them. But one thing is missing: a home of their own. When they find one, it comes with one feature they didn't expect--an upstairs tenant, Mrs. Connelly, who lives in a rent-controlled apartment, and who isn't quite as easy-going or frail as Alex and Nancy originally anticipated. As their blissful life begins to seriously fray around the edges, their dream home rapidly turns into a nightmare and they decide that they must get Mrs. Connelly out of their lives.
