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 find their dream duplex in New York City. The catch? The sweet elderly tenant, Mrs. Connelly (Eileen Essell), shows no signs of leaving, despite their purchase agreement assuming she would pass away soon.

What begins as a simple housing dilemma escalates into increasingly absurd attempts to drive out their seemingly innocent tenant. The film cleverly balances slapstick humor with cringe-worthy situations as the couple's schemes backfire spectacularly. Stiller delivers his signature frustrated everyman performance, while Barrymore provides the moral compass that gradually erodes. Eileen Essell steals scenes as the deceptively sweet Mrs. Connelly, whose innocent demeanor masks surprising resilience.

DeVito's direction maintains a brisk pace throughout the 89-minute runtime, never letting the single-location premise feel stagnant. While the film received mixed reviews upon release, it has developed a cult following for its dark humor and relatable premise about urban housing struggles. The escalating battle between generations makes for entertaining viewing, with the apartment itself becoming a character in this war of domestic attrition.

Viewers should watch Duplex for its sharp satire of gentrification, strong comedic performances, and the universal appeal of its premise. The film offers laughs while posing ethical questions about property, aging, and how far ambition should go. It's particularly enjoyable for fans of dark comedies and anyone who's ever dealt with difficult neighbors or housing dilemmas.
