As far as I know, this is the first movie to place the DIE HARD scenario on a submarine. Michael Dudikoff plays James Carter, an ex-Navy SEAL (what else?) who reluctantly agrees to save the day when terrorists seize control of a nuclear submarine, the same sub he designed. The movie has a good deal of action that keeps the film going, and the production values (for a B-movie) are pretty good. The use of footage from the producers' other movies for the film's underwater sub action and the special effects of a missile destroying part of a New York skyscraper are a bit distracting, but everything else is pretty well done. It would have been nice to have J*A*G*'s Catherine Bell in a bigger part. The story isn't deep or anything, but it has a good pace that never drags, the action scenes are well-choreographed, and the music has a big-budget feel that helps the film. All-in-all, one of Dudikoff's better 90s films. Look for TITUS star Christopher Titus as the sub's comedic, celebrity-impersonating sonar man.
