The success ofUnder Siege made a sequel mandatory according to Hollywood's rules of maximum revenue; and as sequels go; this one's not half bad. Steven Seagal returns as former Navy SEAL and skilled chef Casey Ryback; who's trying to spend quality time with his niece on a cross-country train trip. But as luck and action-movie formulas would have it; the train has been hijacked by a demented genius (Eric Bogosian) who is using the train as a moving platform to seize computerized control of a top-secret U.S. satellite that is capable of causing earthquakes from space. Seagal has to stop the train or the villain (whichever comes first); and the action is fast and furious on its way to a high-speed climax. He's not as wacky as Tommy Lee Jones in the first Under Siege; but Bogosian has got a delirious quality that serves the comic-book plot; and action fans get more than their fill of dazzling stunts and special effects. --Jeff Shannon
