Duplex (2003) is a darkly comedic film that explores the extremes people will go to for the perfect home. Directed by Danny DeVito, the movie follows Alex and Nancy, a young couple played by Ben Stiller and Drew Barrymore, who purchase a gorgeous New York City duplex with one catch: the sweet elderly tenant, Mrs. Connelly (Eileen Essell), has lifetime occupancy rights. What begins as a simple plan to encourage her to move out escalates into increasingly absurd and desperate schemes as the couple's frustration grows.

The film's strength lies in its performances, with Stiller and Barrymore delivering excellent chemistry as the increasingly unhinged homeowners. Essell steals scenes as the seemingly innocent but surprisingly resilient tenant, creating a perfect comedic foil. DeVito's direction maintains a brisk pace throughout the 89-minute runtime, balancing slapstick humor with darker comedic elements.

While the premise might seem simple, Duplex offers clever social commentary about urban living, property obsession, and generational conflict. The escalating situations provide consistent laughs while revealing the characters' moral compromises. For viewers looking for a lighthearted comedy with an edge, Duplex delivers solid entertainment with memorable performances and situations that will resonate with anyone who's ever dealt with difficult neighbors or housing dilemmas.
