In this chapter, we introduce the two main frames deployed throughout the book. The first is conceptual, focusing on political myths and the forms they take in Hollywood film. The nature of such myths is that they are uncritical and provide supposedly timeless explanations. The second framework is historical, identifying the key characteristics of Hollywood eras in order to locate and contextualise their emergent political myths. We use these two frames to show how political mythologies arise from and change in Hollywood movies over time.
