One of the best cold war thrillers ever. Great cast and great writing.
Leonard Maltin/Plot synopsis:
Exciting, complex thriller from the best-seller by Tom Clancy. Connery stars as a Soviet submarine captain who may (or may not) be planning to defect to the U. S. during the maiden voyage of a supersecret nuclear sub; Baldwin is the American intelligence ace who tries to anticipate his every move. Long, potentially confusing at times, but always manages to make a course correction in the nick of time... and deliver another direct hit. Oscar winner for sound-effects editing. Followed by PATRIOT GAMES. Panavision.
