One of the better films made about submarine and anti-submarine warfare, The Enemy Below takes a unique dual view of the action. It's basically a duel between an escort vessel and the U-Boat that they are hunting, a scenario that's been used in other films like it. While it suffers from the obviously propagandist nature of World War 2 films, it's better than most when it comes to the human non-political nature of this kind of warfare. Curt Jurgens plays his German opponent with his usual grim-faced vigor. The depiction of the action is pretty good by the standards of the day, although the plot is somewhat predictable. The destroyer escort depicted is accurate as to class, and actual crew of a real US destroyer escort were extras in the film. The U-Boat set is less impressive, and fails to capture the cramped nature of the small German boats in the Atlantic. Das Boot still remains the best of this genre, but Enemy Below is pretty competent as to tactics and devices used. Based on a book by a former British Navy officer, the whole scenario closely resembles similar ram-and-sink incidents in the North Atlantic convoy actions. Robert Mitchum played a number of naval officers during his long and varied career, but this is one of his better gutsy performances.
