"Boris Karloff's man-made monster is revived in the castle of Frankenstein to provide material for another adventure of the ogre. Basil Rathbone, son of the scientist-creator, returns from America to the family estate, becomes intrigued with the dormant ogre and revives him with idea of changing the brute nature within. There are secret passages and panels; surprise opening of doors; and well-timed sound effects to further create tense interest. For offering of its type, picture is well mounted, nicely directed, and includes cast of capable artists." - Variety Staff, Variety
