"Morocco" was followed by "Dishonored" (1931) with Victor McLaglen, a major success with Dietrich cast as a Mata Hari-like spy. "Shanghai Express" (1932) with Anna May Wong, which was dubbed by the critics ""Grand Hotel" on wheels", was von Sternberg and Dietrich's biggest box office success, becoming the highest-grossing film of 1932. Dietrich and von Sternberg again collaborated on the romance "Blonde Venus" (1932) with Cary Grant. Dietrich worked without von Sternberg for the first time in three years in the romantic drama "Song of Songs" (1933), playing a naïve German peasant, under the direction of Rouben Mamoulian. Dietrich and Sternberg's last two films, "The Scarlet Empress" (1934) with John Davis Lodge and "The Devil Is a Woman" (1935)—the most stylized of their collaborations—were their lowest-grossing films. Dietrich later remarked that she was at her most beautiful in "The Devil Is a Woman".
