I once read the statistics about how many films are made and how many actually get a cinema release. You would expect a film starring Ed Harris, David Duchovny and William Fichtner to make it to the big screen but I guess there is little demand for submarine movies these days. That said this is a very good submarine movie that will keep you enthralled to the end. Harris stars as a washed out and troubled captain who is sent out on one last tour with his first boat, an ageing hulk that is about to be sold to the Chinese. Along for the ride are some 'technicians' led by Mr X Files himself who want to test some new equipment at sea. Ed and his executive officer played by the always excellent Fichtner soon figure out that the these and some new crew members are KGB and find themselves in the middle of a plot to start World War 3 and blame it on the Chinese. Can they stop them and will they survive are the big questions. This is allegedly based on the true story of a Soviet ballistic missile sub that went missing in 1968 and was eventually recovered only to discover that the cause of its sinking appeared to be the missile detonating in its tube, the Soviet choice of fail safe mechanism at the time. All else is conjecture but make for a very entertaining story. Highly recommended in this blu ray is the soundtrack that fills your room with sound if you have the equipment. Close your eyes at any moment whilst they are underwater and you will be surrounded with superb effects. It is almost worth buying just to show off your sound system.
