What a treat it is to see this in widescreen and Panavision – a delightful slow-burn of a romantic adventure spy film, adapted from the classic by Erskine Childers. Written by director Tony Maylam and John Bailey, it tells the tale of Arthur Davies (Simon MacCorkindale) an amateur yachtsman charting the sandbanks of the area around the Frisian Islands off the North German coast in 1903. He is discovered by the sinister Dollmann (Alan Badel) a salvage merchant whose daughter (Jenny Agutter) he befriends. When Dollman runs him aground en route to duck shooting in the Baltic, he contacts his university friend, Charles Carruthers (Michael York) now working in the Foreign Office with an invitation to join him on vacation. The suspicion that England is about to be invaded by the Kaiser using a flotilla of barges is proven correct. Quietly thrilling, incredibly shot (by the great Christopher Challis, whose son, Drummond, produced) this has some nice directorial touches – concealing Carruthers long after we first hear York’s unmistakeable throaty voice, hiding Badel’s real identity behind an impressive hipster beard, retaining a sense of real tension and implacable difference between these very British buddies – not to mention the fabulous sweaters. I really dig the cut of this jib.
