The best Richard Arlen’s science fiction movies

An obsessed scientist conducts profane experiments in evolution, eventually establishing himself as the self-styled demigod to a race of mutated, half-human abominations.

After an astronaut space capsule is detonated in orbit, with the astronaut begging to be killed, a teenager couple finds a severed arm on a remote beach. The boy takes the arm home, where it becomes animate and the alien force which animates it soon possesses his mind as well.

A millionaire's brain is preserved after his death by a scientist and his two assistants, only to create a telepathic monster.

An alien is dispatched from a faraway galaxy to take over the Earth by "duplicating" humans and creating a race of zombies resembling animated pottery in this low-budget sci-fi film. Enjoy the opening and closing shots of the alien spacecraft resembling a Christmas tree bauble dancing in space, the faces of the "duplicated" humans shattering like a cheap vase when thrown to the floor, and the formative "duplicates" as they are cooked up in the lab in individual coffins. The alien's heart is softened by the persevering goodness of a beautiful blind woman, deeply conflicting his motives as the film plods to its "climactic" confrontation between the humans and their counterfeit duplicates.
