This essay analyzes the cinematic genre convention of the “sensation scene” as a vehicle for the representation of queer crises in American juvenility during the postwar era. Through popular cinema, post-WWII America organized and communicated concerns about the production of “fit” masculine and heterosexual juveniles who would be capable of carrying out the postwar expansion of American democratic and capitalist ideologies. The sensation scene was deployed by popular films to mark queer and racialized masculinities in an aesthetic system that mirrored institutional efforts to prevent “unfit” juveniles from accessing the benefits of full social and political participation. Today, the genre device continues to structure popular film representations of and common thinking about the relative value of young, male American lives.
