I am sympathetic to the other reviewers' points of view and note the film's shortcomings. Not a big-budget movie, and was done when I believe the British film industry was hurting in the Fifties. However, I did like the acting of the seasoned British actors in the movie and their banter about their old schoolboy days and Naval service and such. And the look at the history of that time and the strategy and decisions facing the German captain and British commanders was interesting,as were the shots of the old Bristish and New Zealand cruisers on maneuvers and firing, and of the USS Salem, the stand in for Graf Spee. If you are a navophile or history buff and like movies like "In Which We Serve" or "In Harms Way," or "Sink the Bismarck," like I do, you might like this one. I give it a generous 4 stars and I did go out and buy it after I saw it.
The British upper class accents make this film require subtitles - which it doesn't have. This film is incredibly dated and quasi laughable - see it as a period study and be well rested before you launch.
