The idea of the doppelgänger or the double has recently had something of a resurgence, with films and series such as The Haunting of Bly Manor (Flanagan: 2020), Curon (Abbate: 2020-present), Living With Yourself (Greenberg: 2019-present), Two/One (Cabral: 2019), Gemini Man (Lee: 2019), Doctor Sleep (Flanagan: 2019), Us (Peele: 2019), Annihilation (Garland: 2018), Look Away (Bernstein: 2018), Cam (Goldhaber: 2018), Dark (Odar and Friese: 2017–20). These and many others feature doubles, twins or clones and they all see the world that was once familiar and known suddenly become uncanny and threatening; a place of shadows, anxiety and danger creating a gothicised environment that seems intent on our destruction. More importantly, the dark doubles or doppelgängers living in such worlds often seem to have evil intentions to replace, or do away with the original, self-constructing a space where friends and family can instantly become strangers that do not have our welfare in mind. In many senses, these deep and sudden divides between ourselves and the world, and ultimately within our own selves, reflect the combative, partisan nature of the early twenty-first century. Such cognitive and ideological fracturings are literally life-endangering, creating a doppelgänger world that threatens our very existence. Uncanny Doubles explores how such fears are expressed through popular culture, and, in particular, through the figures of the twin, clone or doppelgänger to show how we are living in truly Gothic times.
