In this comedy, a cop assumes a new identity in his valiant battle against crime: an elderly grandmother! Malcolm Turner (Martin Lawrence) is an FBI agent who is a master of disguise and will stop at nothing to get his man. When a bank robber escapes from prison and goes on a violent crime spree, Malcolm is assigned to bring him in. The thief's girlfriend Sherry (Nia Long), who is also the mother of his child, lives in a small Southern town, and Malcolm plans to set up a stake-out in the house across the street from Sherry's. However, the house is owned by Big Momma (Ella Mitchell), an older woman with a sharp tongue and no patience for back talk, and when Big Momma has to leave town, it leaves her house suspiciously empty. Determined to maintain his cover, Malcolm disguises himself as Big Momma, and now has to convince Sherry (and everyone else in the neighborhood) that Big Momma's still in town. Big Momma's House gained considerable pre-production publicity when Lawrence fell into a coma while jogging in a heat wave before the film's start date; Lawrence claimed that he was trying to lose weight to fit more comfortably into his character's "fat suit."
