Factual error: Near the beginning, when the Russian Delta-class sub is locking US cities as potential targets for nuclear missiles, Boston is one of the cities that appears in Russian on the computer screen. However, the way it is written is wrong (it starts with B, the Cyrillic character for V not B, so it appears as Voston).
Factual error: When the U.S. admiral and his staff brief the rep from the White House, the Admiral tells the female Naval Intelligence officer to brief the official. He calls her "Lieutenant", although her collar insignia indicates she is a Lieutenant Commander and he would thus, in shorthand, call her "Commander." (00:37:00)
