Before revealing any plot details for his second feature, in May 2018 Jordan Peele shared on Twitter a poster image: a Rorschach-style inkblot rendering of two women. It was our first glimpse at the film's doppelganger motif and Lupita Nyong'o's dual role as middle-class mother Adelaide Wilson and her monstrous double, Red. In Monstrous Possibilities, Lucy Baker and I (Howell and Baker 2022) observe the prevalence of the doppelganger in contemporary horror entertainments featuring monstrous female protagonists, noting how it recalls the female Gothic's depiction of repressed subjectivities and their return.
