Martin Lawrence embraces his feminine side once again in this uninspired sequel to the smash-hit comedy. When a deadly computer "worm" threatens national security, FBI agent Malcolm Turner (Lawrence) disguises himself as chubby grandma Hattie Mae Pierce and poses as a nanny to infiltrate the home of suspect Tom Fuller (Mark Moses). Unsurprisingly, chaos ensues as Big Momma tries to juggle law enforcement and "her"own unconventional take on domestic perfection. With its tired plot and weak dialogue, the film is forced to focus on cheap, visual gags, getting extensive comic mileage from the idiosyncrasies of Momma and her three dysfunctional charges. Director John Whitesell (Malibu's Most Wanted) works hard to keep the humour flowing, but despite occasional moments of crude hilarity, there's just not enough substance here to justify this lazy cash-in.

FBI agent Malcolm Turner goes back undercover as Big Momma, a slick-talking, slam-dunking Southern granny with attitude to spare! Now this granny must play nanny to three dysfunctional upper-class kids in order to spy on their computer hacker father.
