In the late sixties, Spanish cinema began to produce a huge amount of horror genre films: international markets were opened, the production was continuous, a small star-system was created, as well as a solid group of specialized directors. Although foreign trends were imitated, Spanish horror offered a particular approach to sex, blood and violence. It was an extremely unusual artistic movement in Franco's Spain.
