The poster for Saul Bass's 1958 film Vertigo approaches subjects like anxiety, disorientation and horror through its use of a red background and handwritten title. The spiral design in the center is meant to confuse viewers in a way that relates to the film's exploration of mental health issues. While some elements seem to target an older audience due to these complex themes, the author argues that the poster could appeal to anyone interested in thriller or horror films regardless of gender. The key photo-mechanical portraits of the main characters make them seem more real and relatable to the psychological concepts addressed in the film. Overall, the unconventional poster style uses symbolism to intrigue audiences and highlight the unusual nature of the film.
