The forties was not a good time for SF movies. But the genre sputtered along with mad scientist B-movies turned out by Hollywood. The decade produced none of the immortal classics of the twenties and thirties, but hidden among the low-budget dregg, one can find a few genuine gems worthy of more recognition.
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
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
