Mistress of the World (German: Die Herrin der Welt, French: Les mystères d'Angkor, Italian: Il mistero dei tre continenti) is a 1960 science-fiction spy film remake of the 1919 eight-part silent film The Mistress of the World directed by William Dieterle and starring Martha Hyer and Carlos Thompson. It marked the comeback in his native country of the director William Dieterle after several decades spent in Hollywood. In West Germany, it was released in a longer version split in two parts (Die Herrin der Welt - Teil I and Die Herrin der Welt - Teil II).
