Speculative Imperialisms: Monstrosity and Masquerade in Postracial Times explores the(settler) colonial ideologies underpinning the monstrous imaginings of contemporary popular culture in the Britain and the US. Through a close examination of District 9, Avatar, Doctor Who, Planet of the Apes, and steampunk culture, Susana Loza illuminates the durability of (settler) colonialism and how it operates through two linked yet distinct forms of racial mimicry: monsterization and minstrelsy. Speculative Imperialisms contemplates the fundamental, albeit changing, role that such racial simulations play in a putatively postracial and post-colonial era. It brings together the work on gender masquerade, racial minstrelsy, and postcolonial mimicry and puts it in dialogue with film, media, and cultural studies. This project draws upon the theoretical insights of Stuart Hall, Homi K. Bhabha, Edward Said, Philip Deloria, Michael Rogin, Eric Lott, Charles Mills, Falguni Sheth, Lorenzo Veracini, Adilifu Nama, Isiah Lavender III, Gwendolyn Foster, Marianna Torgovnick, Ann Laura Stoler, Anne McClintock, Eric Greene, Richard Dyer, and Ed Guerrero.
