This chapter considers the ambiguous utopian impulses of literary, filmic, and television works published and produced in the 1970s. Drawing on the concept of post-imperial melancholy, the chapter traces the utopian contours of these texts’ forceful, often shocking, critique of British imperial nostalgia. It focuses on sub-genres that emerged during this significant decade, including the British alternate history, the dystopia, and reworkings of the classical literary utopia, with reference to writers such as Daphne Du Maurier, Len Deighton, Anthony Burgess, Emma Tennant, Angela Carter, and J. G. Ballard. These three genres, the chapter argues, critically interrogate the utopian impulse in the 1970s and its possible instantiations in national and transnational imagined communities, as well as the built environment in which the modernity of these communities is expressed. The chapter concludes with an analysis of Derek Jarman’s Jubilee, identifying how this iconic 1970s punk film reframes the classical narrative structure of literary utopias.
