"The Devil's in Love is a programmer, pure and simple.... In a plot sense, it is fairly formularized, though Harry Hervey-author of Shanghai Express-gives it some typically exotic touches. However, (German emigré) Dieterle and cameraman Hal Mohr give it exciting visual flair; one shot of a cemetery, all shadows and angled crosses, looks for all the world like something from Lang's Destiny! And predictable or not, it takes minimum time to zip through its cliches, is well-mounted, and is nicely played. One of its more surprising elements is the unbilled appearance of Bela Lugosi in a small but key role, in which his distinctive voice heralds his appearance before he is actually seen." William K. Everson
