"John S. Robertson's vision is not boggled down by repetition or clichés, and he breaks from the shackles of Stevenson's immortal story in every detail. The scenes preceding the transformation have a light and delicate touch to them, but it is the dank and menacing scenes afterwards that seem to grab our attention the most. Most of the characters, during the transformation, are seen walking around in damp alleys, in which the light of a lamppost is the only relief from the shadows. One might even call these scenes early examples of the 1940s film noir. "Dr. Jekyll And Mr. Hyde" is not just a movie about unleashing our dark sides, but controlling them." - David Keyes, Cinemaphile
