It’s a strange situation when assistance isn't offered during times of need, but then appears unexpectedly later—especially when it’s not warranted. Shanghai Express is the work of director Josef von Sternberg, with Jules Furthman handling the adaptation and Harry Hervey contributing to the story. The film features Marlene Dietrich, Clive Brooks, Anna May Wong, Warner Oland, Eugene Palette, and Lawrence Grant. Music comes from W. Franke Harling & Rudoplh G. Kopp, while Lee Garmes served as cinematographer. The narrative centers on Shanghai Lily (Dietrich) reconnecting with her former lover, Donald Harvey (Brooks), aboard the Shanghai Express during the Chinese Civil War in 1931. The train carries a diverse group of passengers, each harboring secrets, and when rebels attack, underlying allegiances, relationships, concealed intentions, and the emergence of notable figures are revealed. Sternberg’s visually striking direction, combined with a more rapid pace than his other films featuring Dietrich, makes Shanghai Express stand out due to its compelling atmosphere, well-written script, and Dietrich's captivating performance. The limited space on the train enables Sternberg to utilize shadows, smoke, and beams of light—a technique that earned Garmes an Academy Award—while the supporting cast delivers understated but fascinating portrayals. The film demonstrates a high level of artistry both in front of and behind the camera, as well as from those who wrote it. 8/10
