Universal’s House of Frankenstein sees Boris Karloff as a mad scientist hiring Dracula as a hit man, attempting to cure the Wolf Man and restart the Frankenstein monster. All while J. Carrol Naish’s hunchback is trying to bonk a gypsy girl who’s in love with the werewolf. While the nutty story can be entertaining, this 1944 film’s downfall is its contrived plot and structure. 4/10
Braaaaaiiiins! The first adaptation of Curt Siodmak’s cult novel Donovan’s Brain turns up the mad scientist factor to eleven. The 1944 film sees Erich von Stroheim as the resident Frankenstein, as a disembodied brain takes control over his assistant’s mind. Atmospheric cinematography and an overall strong cast compensates for ice skater Vera Hruba Ralston’s lack of acting experience in the female lead. 5/10
Horror icons George Zucco and John Carradine join Bela Lugosi in his last film at Poverty Row studio Monogram, for one of the most bizarrely funny so-bad-it’s-good sci-fi horror films of the forties. Unfortunately giggles aren’t enough to lift this film out of the ruts, although it is a must-watch for the wonderful Voodoo seances with Carradine and Zucco immensely enjoying the insanity of it all. 2/10
A good black supporting cast led by comedian Mantan Moreland saves this 1943 film, directed by The Day of the Triffids director Steve Sekely. John Carradine sleepwalks through his second outing as a mad scientist, this time creating zombies out of his staff and even his own wife. The white heroes of the movie are really just killing time between Moreland’s comedy skits. 4/10.
Director Edward Dmytryk cuts and pastes together a surprisingly coherent and enjoyable tale of a gorilla being turned into a woman by a nutty John Carradine in his first mad scientist role. The 1943 film made the mysterious Acquanetta an over-night star, and garnered two sequels, despite the fact that one third of the movie is reused footage from an old lion-taming film. 5/10
A quick Universal cheapo from 1941, this was the first of Lon Chaney Jr.’s monster movies, and one of his best. Lionel Atwill shines as the mad doctor who pumps Chaney full of electricity, until he becomes a mindless, glow-in-the-dark monster who kills with a touch. 6/10
The fourth and best of Columbia’s Karloff mad scientist films takes an eerie dip into Lovecraftian cosmic horror. Directed by later Oscar winner Edward Dmytryk, it unfortunately falls back on tired B-movie tropes, but it’s still a minor gem of forties science fiction. 7/10
