Her legs are waxed, her lips are glossed, her gun in ready. FBI Agent Gracie Hart is going undercover as one of the hopefuls eager to be next Miss United States. But Gracie, whose idea of a fashion accessory is the set of handcuffs she slaps onto lawbreakers, doesn't have a beauty-pageant bone in her body. Sandra Bullock gets physical in Miss Congeniality, bringing her powerhouse talent for physical comedy to the role of an operative posing as a pageant contestant in order to ferret out a terrorist targeting the event. Michael Caine deliciously plays the frustrated consultant hired to turn the FBI's Dirty Harriet into a poised beauty. And Benjamin Bratt, Candice Bergen, William Shatner and Ernie HUdson also score points for hilarity in this box-office smash in which "My Fair Lady meets Lethal Weapon" (Sara Edwards, NBC- TV/Boston). From big laughs to sly quips, Miss Hits.
