Writer/producer/director George Seaton’s penchant for realism and drama-documentary style gets a full airing here in an adaptation of Alexander Klein’s titular nonfiction book. The great (and prematurely aged – he was 44 and looks 64 at least) William Holden plays the American born oil man Eric Erickson, resident in Sweden and doing his usual cross-border deals – including with Germany – who is blackmailed into espionage for the Allies in the form of the smirking Hugh Griffith. In Germany he becomes involved with a religiously inclined agent Marianne Moellendorf (Lilli Palmer) who ends up being found out in a confessional, and Erickson then struggles to escape Berlin after betrayal by his friend’s son, a member of the Hitler Youth. This morality tale is long and engrossing and Holden gets the opportunity to play a whole range of emotions under Seaton’s careful direction. The camerawork (by Jean Bourgoin) is mostly static in keeping with this realistic mode but there are some great shots of the rubble of Berlin and the encounter in the church confession box is particularly well staged. It’s great to see these post-war cities in colour, another boon to an involving story. And the startling Klaus Kinski is key to the conclusion. If you ever want the dogs that torment you to take a walk on the wild side well away from you, try a combo of blood and cocaine. It’s amazing what tips you pick up in movies.
