Two experiments were conducted to explore the contributions of sexual and violent images contained in movie previews on viewers’ anticipated perceptions and enjoyment of previewed films. In neither study were portrayals of sex or violence directly associated with greater anticipated enjoyment. However, both studies provided evidence that sexual and violent portrayals may indirectly enhance viewers’ enjoyment via perceptions of heightened suspense (Study 1) or heightened humor (Study 2). These results are discussed in terms of viewers’ responses to media images of sexuality and violence, and the importance of these portrayals in the marketing of motion pictures.
