After recovering from injuries sustained in the mob attack upon himself and his creation, Dr. Frankenstein falls under the control of his former mentor, Dr. Pretorius, who insists the now-chastened doctor resume his experiments in creating new life. Meanwhile, the Monster remains on the run from those who wish to destroy him without understanding that his intentions are generally good despite his lack of socialization and self-control.
Ernest Thesiger is superb in James Whale's sequel to "Frankenstein" as the scientist who has perfected the art of growing rather than harvesting tissue. When he meets up with Baron Frankenstein's original monster they set about coercing the reluctant Baron to create a wife for the lonely Boris Karloff. This is a cracking tale of science fiction, horror and even romance as the monster ends up endowed with far more "humanity" than either scientist. Una O'Connor and Elsa Lanchester are both great too, though feature sparingly. The special effects stand better scrutiny than many a sci-film being made twenty years later and the cannibalised classical musical score brings tension, joy, love and despair a-plenty to compensate for, admittedly a rather stilted script. Easily the best "Frankenstein" film ever made in my book.
