During World War 2, the horror genre shifted from Britain to America as horror films were banned in Britain. Hollywood began producing more horror films to entertain domestic audiences. These 1940s horror films often featured creatures influenced by the war, including Frankenstein, werewolves, and cat people. One influential film was 1941's The Wolf Man, which established werewolf tropes and was influenced by propaganda depicting Hitler as the "Big Bad Wolf". Another success was 1942's Cat People, a psychological thriller presenting women as dangerous beings. However, the genre moved to less artistic, more comedic sequels and crossovers that diluted the scare factor of the classic monsters.
