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 studios that worked on horror films during society's piqued interest in the genre. Universal's monster films focused mainly on the physical monsters present in their films. In contrast, films produced by RKO focused less on actual, physical 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” than monsters.
