An examination of male screen sex appeal and the ways that race, ethnicity, and national origin combine with performance tools and film and television style to aid or inhibit actors' circulation on an increasingly global stage. Sex appeal is complicated, especially for screen actors. Looking good is not enough. Charisma and charm have to register when the camera rolls. And sexiness has to travel. Today's heartthrobs are expected to raise temperatures all around the world. Cosmosexuals theorizes male sex appeal as a form of capital in an age of international stardom. Screen scholar Mark Gallagher assembles a diverse cast - Idris Elba, Pedro Pascal, Simu Liu, Ryan Gosling, and more-analyzing how each actor uses his appearance, voice, and movement to perform in ways that viewers across cultural divides register as sexually appealing. Cosmosexuals also explores the intersection of global sex appeal and exoticism in historical and contemporary contexts-from the malleable racial identities of Omar Sharif and Conrad Veidt to Mads Mikkelsen's "accented whiteness"-and assesses the barriers that confine nonwhite actors, in spite of their talent or celebrity. Far more than handsome faces and chiseled abs, male sex symbols emerge as laborers subject to disciplinary regimes steeped in patriarchy, racism, and structural inequity. As such, they have much to tell us about the economies of taste at work in the construction of screen masculinity and the terms of human desire.
