One Good Cop (released in theaters on May 3, 1991) stars Michael Keaton as Artie Lewis, an honest New York City police detective whose life is upended by a tragic shootout. When his partner and best friend, Stevie Diroma (Anthony LaPaglia), is killed in the line of duty, Artie and his wife Rita (Rene Russo) find themselves at a moral crossroads.
Stevie, a widower, has left behind three young daughters who face being separated by the foster care system.
Driven by a sense of duty and love, Artie and Rita decide to take the girls in, but they quickly realize that their modest lifestyle and Artie’s detective salary cannot accommodate a family of five – especially when they need a larger home to satisfy the state’s requirements.
The plot thickens as Artie’s desperation grows, leading him to cross the thin blue line he has spent his career defending.
He targets a ruthless drug lord, planning to steal drug money to provide for the children.
Director Heywood Gould balances the procedural elements of the film with a tender domestic drama, supported by a strong ensemble cast including Benjamin Bratt as a fellow officer and Rachel Ticotin as a sympathetic detective.
Keaton delivers a powerhouse performance, showcasing the frantic, high-wire energy that became his trademark, tempered here with a profound, weary fatherliness.
His chemistry with Russo is authentic, making the couple’s struggle feel grounded and urgent rather than melodramatic.
LaPaglia is equally memorable in his brief but impactful role, providing the emotional catalyst for the film’s second half.
Kevin Conway, Tony Plana, Kevin Corrigan, Vondie Curtis-Hall, George Cheung, and Brigitte Bako round out the cast.

Reception for One Good Cop
One Good Cop grossed $3.4 million on its opening weekend, finishing second at the box office behind Oscar ($4.2 million) starring Sylvester Stallone.

Legacy
The legacy of One Good Cop lies in its position as a quintessential “transitional” drama of the early 1990s, bridging the gap between the hyper-violent action films of the 80s and the more nuanced, character-driven police procedurals that would later dominate television.
While it may not have launched a massive franchise, it remains a cult favorite for its willingness to explore the gray areas of morality and the crushing weight of systemic poverty on civil servants.
It serves as a testament to Keaton’s range, proving he could carry a gritty urban thriller with as much gravitas as a comic book blockbuster.
Ultimately, One Good Cop is remembered as a poignant exploration of what it truly means to be a “good” man in an indifferent world, blending visceral street tension with a deeply moving story of unconventional fatherhood.
