Some disguises are meant to hide you. Others reveal who you really are. Big Momma’s House 4: Family Undercover (2026) brings back the outrageous charm of undercover chaos, led once again by Martin Lawrence, alongside the sharp comedic brilliance of Regina Hall, the magnetic energy of Keke Palmer, and the rapid-fire humor of Kevin Hart. This fourth installment doesn’t just revisit the wig and floral dresses — it reinvents the stakes.
Malcolm Turner thought he had retired the Big Momma persona for good. But when a high-stakes federal operation collides with a deeply personal family emergency, there’s only one solution: bring Big Momma back — and this time, bring the whole family into the mission. What begins as an undercover assignment quickly spirals into a layered operation involving mistaken identities, neighborhood gossip, and secrets that hit far too close to home.
Martin Lawrence slides effortlessly back into the iconic role, proving that Big Momma isn’t just a disguise — she’s a full personality. The humor remains physical and unapologetically exaggerated, but there’s an undercurrent of reflection. Malcolm is older now, and the act of hiding behind Big Momma forces him to confront what he’s been avoiding in his real life.
Regina Hall delivers razor-sharp timing, grounding the absurdity with intelligence and poise. Her character isn’t fooled easily, and her suspicion injects delicious tension into the narrative. She balances comedy with subtle emotional depth, ensuring the story never floats too far into parody.
Keke Palmer brings a vibrant modern edge, representing a younger generation that refuses to be sidelined. Her character’s tech-savvy confidence contrasts hilariously with Big Momma’s old-school methods. The generational dynamic becomes one of the film’s most entertaining elements.
And then there’s Kevin Hart — a walking catalyst for chaos. His energy is relentless, his reactions explosive. Yet beneath the rapid punchlines lies a surprisingly loyal presence, adding heart to the undercover madness.
The film thrives on escalation. A simple stakeout turns into a neighborhood cookout. A quiet interrogation explodes into a church choir rehearsal. Each scene builds upon the last, stacking absurdity until it teeters on collapse — and somehow sticks the landing.
But Family Undercover isn’t content with recycled jokes. It explores identity in a way earlier installments only hinted at. Who are we when we’re pretending? And what happens when the mask becomes more comfortable than reality?
Visually, the movie embraces bright suburban settings that contrast with the covert operation unfolding beneath the surface. Floral kitchens and pastel living rooms become espionage arenas. The contrast fuels the comedy — domesticity meeting danger.
There are moments where the laughter softens. Conversations about trust. Confessions about fear. A realization that protecting family sometimes means telling them the truth rather than shielding them from it.
As the climax barrels toward a chaotic reveal, the film leans into spectacle — disguises unravel, alliances shift, and secrets spill. Yet the resolution centers not on the mission’s success, but on reconciliation.
Big Momma’s House 4: Family Undercover (2026) proves that while disguises may change, family remains the most complicated operation of all. And sometimes, the bravest thing you can do isn’t going undercover — it’s stepping out of it.
