This book demonstrates the political potential of mainstream theatre in the US at the end of the twentieth century, tracing ideological change over time in the reception of US mainstream plays taking HIV/AIDS as their topic from 1985 to 2000. This is the first study to combine the topics of the politics of performance, LGBT theatre, and mainstream theatre’s political potential, a juxtaposition that shows how radical ideas become mainstream, that is, how the dominant ideology changes. Using materialist semiotics and extensive archival research, Juntunen delineates the cultural history of four pivotal productions from that period—Larry Kramer’s (1985), Tony Kushner’s (1992), Jonathan Larson’s (1996), and Moises Kaufman’s (2000). Examining the connection between AIDS, mainstream theatre, and the media reveals key systems at work in ideological change over time during a deadly epidemic whose effects changed the nation forever. Employing media theory alongside nationalism studies and utilizing dozens of reviews for each case study, the volume demonstrates that reviews are valuable evidence of how a production was hailed by society’s ideological gatekeepers. Mixing this new use of reviews alongside textual analysis and material study—such as the theaters’ locations, architectures, merchandise, program notes, and advertising—creates an uncommonly rich description of these productions and their ideological effects. This book will be of interest to scholars and students of theatre, politics, media studies, queer theory, and US history, and to those with an interest in gay civil rights, one of the most successful social movements of the late twentieth century.
