Rating: Null/10 (20 August 2003)

A story about a submarine so flawed, during construction it was named "the Widowmaker." I was a teenager in 1961, the time period for this movie, "K-19, Widowmaker." I recall the cold war posturing by the USA and the Soviet Union, and this movie dramatizes the fate of the newest Soviet nuclear submarine. Harrison Ford and Liam Neeson star as the Captain and his first mate, the former Captain. Ford plays a taskmaster who won't let up, won't quit having is new crew practice emergency drills, even when some of them become injured, because he suspects their fate will depend on how well the crew will respond when a crisis really arises. A bit slow in the middle, still, a good movie.
SPOILERS follow, please read no further.
After breaking through the Arctic ice, and a successful test missle launch, the sub and crew are assigned to patrol the Atlantic east of the NY and DC areas. A leak develops in the nuclear reactor section, cooling is lost to one reactor, and if not arrested would heat to the point of destroying the sub, killing all aboard, and perhaps detonation of nuclear weapons aboard. A fix is planned, but requires entering the reactor chamber without proper radiation clothing, 10 minutes per person, radiation burns and sickness, vomiting, fix works but sub crippled, deadly radiation spreading aboard sub, mutiny is attempted, USA ship offers help, rejected, a Russian sub shows up, defied Moscow orders and get men off ship, court martial, aquitted, he and crew sworn to secrecy, until the 1989 fall of the Communistic regime in the USSR, when the whole crew gathered to honor the dead, and to toast the Captain.
Good movie, especially for those of us who lived through the period.
