The Mysterious Dr. Fu Manchu is a 1929 American pre-Code drama film directed by Rowland V. Lee and starring Warner Oland as Dr. Fu Manchu. It was the first Fu Manchu film of the talkie era. Since this was during the transition period to sound, a silent version was also released in the United States, although only the sound version exists today.
Plot: A young white girl, Lia Eltham, is left in Fu Manchu's care. A British regiment, chasing Boxer rebels, fires on Fu Manchu's home, killing his wife and child. When Lia Eltham grows up, he uses her as an instrument for revenge, killing all descendants of those who killed his family. Opposing Fu Manchu are Police Inspector Nayland Smith and Dr. Jack Petrie.
