Very good movie. Navy was always considered the elite of Russian (and many others) armed forces and the elite of the Navy is submarines, after watching this movie one can understand why.
This film is interesting, in a National Geographic kind of way. The story was good, characters interesting and likeable, but not a whole lot of sizzle. Great film if you are into Russian nuclear submarine program. My wife hated it.
While this flick was mostly filmed in my home town of Halifax it has alot to be desired. Neeson is by far the best presentation in the flick, but he had no competion from Ford. See this as a last resort.
