This is a film of considerable charm and interest, a postwar noir updating of the Warner Bros. "Casablanca"-style foreign intrigue routine that substitutes a refreshing toughness for the earlier films' cotton-candy romanticism. As usual, the stalwart leading man plays second fiddle to the character roles. Claude Rains takes his wry-and-witty routine to the level of sublime high camp, Peter Lorre purrs lyrical philosophy in a rumpled linen suit and three-day beard, and Paul Henried does much better as the arrogant, sadistic villain (reminiscent of Ronald Merrick in "Jewel in the Crown") than he ever did as a leading man. There's even subtle criticism of the apartheid system thrown in. What could have been a minor classic and certainly the best of the "Casablanca" clones is severely compromised however by the presence of Corinne Calvet, whose ferret face and rusty-hinge voice make a potentially pleasurable film difficult to watch, let alone enjoy.
