Slasher and psychological movies began to show on the big screen, focusing on the fears from inside an individual and movies began to use the audience's mind and fears to trick them, bringing out inner horrors. As well as this, there was a move into colour meaning the technological development allowed special effects and movies to appear creepier. With a focus on religion as well as the devil, more conventions began to be used. Motifs such as fear of the devil, good and evil, females as a threat, violence, hidden evil and inhuman beings emerged. Rosemary's Baby (1968) and The Night of the Living Dead (1968) were some of the movies around this time.
