The last time Martin Lawrence made the news, he was roasting himself to death by jogging in three layers of clothing in 100-degree heat. Maybe he was conditioning for this role, in which he packs on layers of latex to play an undercover cop who disguises himself as an overweight elderly woman in order to catch a bank robber. Hitting the mark with most of his well-timed jokes, Lawrence only falls down when he means to.
He surrounds himself with top-notch professionals, like the beautiful Long and the diverse Giamatti, to keep the movie's pace quick. Gosnell fattens up his reputation for creating lighthearted comedies (like last year's Never Been Kissed), so audiences can expect laughs as large as Big Momma's girdle.
