I have never read any of the Jack Ryan books by Tom Clancy so I don't know how faithful of an adaptation this production was. That said, director Phillip Noyce does a competent job here in blending the realistic-looking (to my untrained eye) action sequences with the dialogue scenes to create some genuine suspense and tension. To be honest though, I watched this only because Harrison Ford was starring. In 1994, he was still the quintessential action hero in cinema (some say he has been for 30 years). In fact, when Nicolas Cage started making action movies in the mid-nineties, he said he modeled much of his work on Ford's. That has to be one of the highest compliments one leading man can give to another!
