In this wholly original work of film criticism, David Thomson, celebrated author of The Biographical Dictionary of Film, probes the many ways in which sexuality has shaped the movies - and the ways in which the movies have shaped sexuality. Exploring the tangled notions of masculinity, femininity, beauty, and sex that characterize our cinematic imagination - and drawing on examples that range from advertising to pornography, Bonnie and Clyde to Call Me by Your Name - Thomson illuminates how film as art, entertainment, and business has historically been a polite cover for a kind of erotic seance. In so doing, he casts the art and the artists we love in a new light, and reveals how film can both expose the fault lines in conventional masculinity and point the way past it, toward a more nuanced understanding of what it means to be a person with desires.
