This movie is a cold war tale of an American destroyer hunting a Soviet submarine. The tension builds up wonderfully throughout the film and eventually explodes, both on personnel and greater levels. Tension is present between the skilled but hard nosed captain(Richard Widmark) and a reporter sent aboard(Sidney Poitier). The captain also faces off against the ship's new doctor. Widmark and Poitier both give simply outstanding performances. This film is about them, not explosions or battle scenes. The supporting cast also gives fine performances, including Martin Balsam as the doctor and Eric Portman as a German submarine commander on board as an advisor. It has been said that this film inspired the recent production "Crimson Tide"(which I believe is much less impressive), and after watching you can see why. In turn, I think it is also possible that the producers and writers of "The Bedford Incident" were influenced by "Dr Strangelove" which came out the previous year. While this a drama, not a black comedy, there are some parallels.
