The B Word explores the ways bisexual fantasy opens a space for "bi-curious" engagement, creating a fluid range of identifications and pleasures. In films as diverse as Brokeback Mountain, The Wedding Crashers, Persona, Chasing Amy, and Mulholland Drive, Maria San Filippo finds that bisexual tropes reveal the workings of our culture's logic of desire. Viewing these and other films through a bisexual lens, which views subjectivity and eroticism as malleable, The B Word transforms understandings of films previously read exclusively as either homosexual or heterosexual. As San Filippo's analysis of the promotion and popular reception of these films reveals, the entertainment industry both exploits and effaces bisexuality in its appeal to diverse audiences.
