Sheesh, I thought it would take a little longer than that!
The movie (which goes under two titles: "The Battle of the River Plate" and "Pursuit of the Graf Spee") was on TCM cable a week or so ago; that's why it was on my mind. It has a lot to recommend it. The names of the ships that "played" the Graf Spee, Achilles, Exeter, and Ajax are listed in the opening credits; it's the only movie I've ever seen that does such a thing. In general, the producers seem to have taken a great deal of trouble to make it as accurate as they could - subject to some pretty severe budgetary limitations. Anthony Quayle plays Commodore Harwood, and a very young Christopher Lee (before he made a name for himself in horror movies) has an interesting role as a radio reporter in Montevidea. If I remember right, one of the British merchant captains captured by the Graf Spee plays himself.
It has one strange feature that I've never been able to figure out, in all the times I've watched it. Captain Langsdorff, played by the distinguished British actor Peter Finch, is presented quite sympathetically. But the story ends with the scuttling of the ship. As I remember, the last shot shows Langsdorff standing on board a tugboat, looking pensively on as the Graf Spee burns. There's no mention of the fact that he went back to his hotel room in Montevideo and shot himself. I wonder why the moviemakers left that out.
Bondoman - you're up.
