What it is is an interesting film from the great German director Ernst Lubitsch with early appearances by Pola Negri and Emil Jannings.
Pola Negri plays Ma, a dancer who is kidnapped and held in an ancient Egyptian temple. She is rescued and flees to London with her mysterious captor following her. Emil Jannings lays Radu, a mysterious and sometimes comical Arab. Harry Liedtke provides a bit of romance as the painter Albert Wendland.
(An interesting note and completely off-topic: Liedtke was killed in 1945 by Red Army soldiers when he tried to prevent the rape of a young girl.)
The tagline for this film was: "Bewitching Pola Negri as an Oriental dancer who comes from the burning Sahara to capture London society by storm. All the charm and mystery of the East caught into a passion-swept romance irresistible appeal."
Enjoy this film, but watch out...because "The eyes are alive!"
