We've got trouble. Big trouble * * BIG TROUBLE IN LITTLE CHINA. Kurt Russell, Kim Cattrali. Directed by John Carpenter. At area theaters. Running time: 1 hour, 40 minutes. Rated PG-13. . T SHE "Big PRESS Trouble mystical RELEASES say in Little China" is action/adven- ture/comedy/kung-fu/monster/ghost story," which is a nice way of saying "stir-fried mess." Jack Burton, the unshaven hero, is a sloppy good-natured Joe who, with a little encouragement, turns out to be a regular Indiana Jones. It starts when his Chinese-American buddy (Carter Wong) loses his green-eyed girl to a 2,000-year-old man. Lo Pan, Chinatown's most feared resident, may be showing his age, but he longs to meet a green-eyed beauty who can break the spell which condemns him to live as an evil spirit instead of a flesh-and-blood man. Burton is naturally skeptical of this old Chinese black magic: "Two thousand years and he can't find a broad to fit this bill- come on." Butsoon he's leading a parade of wouldbe rescuers into the gloomy depths of Lo Pan's mansion. This house tour may give young viewer a few kicks- it includes nasty encounters with Lo Pan's high-flying henchmen, a sewer monster and his press agent (a giant talking head). LO PAN, the 2,000-year-old man The perils don't discourage Burton. "Relax," he tells his jittery leading lady, played by Kim Cattrall. "I'm here." Watching Kurt Russell display not only a set of bulging biceps, but also this easy-going self-confidence is admittedly fun at times, even if the movie is as impenetrable as chop suey. -Kathleen Carroll
