THE DEVIL BAT (1940)
He’s Trained His Brood of Blood-Hungry Bats to Kill on Command!
Directed by Jean Yarborough, The Devil Bat stars Bela Lugosi at his best as a scientist Dr. Paul Carruthers who develops formulas for a cosmetic empire that makes two families their fortunes– the Heaths and the Mortons, while he remains a measly worker in his lab.
To exact revenge he creates a race of giant bats to attack and kill off those who have slighted him. Anyone who wears his strong-smelling after-shave lotion is doomed to die!
