Dark Journey

Stockholm, 1918: a French spy running a high-fashion dress shop, played by Vivien Leigh, falls for the German counterintelligence chief assigned to catch her, played by Conrad Veidt. Both know what the other is; neither can quite stop. Victor Saville directs the London Films production as an elegant cat-and-mouse romance where every ballroom scene doubles as tradecraft. Leigh, on the verge of Gone with the Wind, and Veidt, the great German exile who had played Cesare in Caligari, make an improbably magnetic pair, and the neutral Swedish setting lets the film keep its sympathies ambiguous. It is in the public domain in the United States.
