Tony Maylam (and Christopher Challis - read his autobiography, "Are they really so awful") went all-out in this film to recreate a feel for Erskine Childers's slightly jingoistic novel, and for the joy of messing about in boats. The film achieves much of what it set out to do, but some extra elements grafted on to the original plot slightly spoil it for me.
The plot features Davies, an English amateur yachtsman (brilliantly played by Simon MacCorkindale) who stumbles onto something strange while pottering around the bleak Friesian coast in northern Germany. Mystified, he summons his old friend Carruthers (Michael Yorke) to help uncover the secret.
As a detective tale or spy story viewed through the eyes of either Davies or Carruthers, the film works. The few action sequences, which are almost always seen from the viewpoint of others, tend to fall flat and spoil the overall continuity. The subtitles to scenes in which characters are speaking in German are annoying, since almost everything is also translated verbally for the benefit of Davies who does not speak the language.
That said, this is quite a tense film, and gives a very true rendering of the novel.
The scenery and props are quite superb. Davies's yacht is a joy to look at from the outside and suitable poky in the interior shots. The flat coastal scenery is very atmospherically shot and the costumes are very good.
Except for a rather wooden "Kaiser Bill", the acting is excellent, though this is no less than one would expect from such as Alan Badel and Jenny Agutter.
This film is very enjoyable, but best watched with one's thinking cap on.
