This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book describes the characters that dominated the fiction and film narratives of the period: the heroes, villains, and love-interests of popular culture. It addresses the role of the hero as a character who embodies traits collectively valued by readers and the audience. The book presents interwar anxieties about social mobility among both men and women, the acquisition of wealth by businessmen through profiteering, post-war unemployment, and a government that could not entirely be trusted. It looks at the British Board of Film Censors (BBFC) and the Home Office's efforts to endorse the above characters through censorship. The book ends by considering the endurance of the breadwinner and soldier ideal beyond the 1920s and 1930s.
