That’s one reason why Frankenstein, the tale of a frightful beast reanimated from the corpses of other men, remains so enduring: The monster stands as a powerful warning about the price of “progress.” As a fictionalized Shelley explains in Bride of Frankenstein (1935), “My purpose was to write a moral lesson: the punishment that befell a mortal man who dared to emulate God.”
Another explanation? Frankenstein is the rare horror movie that elicits sympathy for its monster. “I think the secret is that the monster’s a misfit, and he’s lost,” says Gregory William Mank, film historian and author of It's Alive! The Classic Cinema Saga of Frankenstein. “Everybody feels like that sometimes. The monster is a profoundly sad being in the films—particularly when [Boris] Karloff was playing him. This incredible sadness, it sounds a chord with people.”
Widely regarded as the quintessential monster movie, 1931’s Frankenstein—along with Dracula, also released by Universal Studios that year—alerted industry executives to a winning strategy: Horror sells. What followed was the unleashing of a string of classic movies centered around so-called “Universal Monsters,” including the Wolf Man, the Mummy, the Invisible Man and the Black Cat.
