The horror genre produced many monster movies like "Dracula (1931)", "Frankenstein (1931)", "The Invisible Man (1933)", "The Bride of Frankenstein (1935), and "The Mummy (1932)". Universal and RKO are examples of two studios that worked on horror films during society's piqued interest. RKO producer, Val Lewton, and the film directors working under him focused less on actual monsters and focused more on “unseen terrors” in their horror movies. "Tourneur's Cat People (1942)" and "I Walked with a Zombie (1943)" are movies that focused more on “unseen terrors”. Choosing to take a less abstract route than their rival, Universal's monster films focused mainly on the physical monsters present in their films.
