With her politically engaged writing and innovative adaptations, Stef Smith is one of the most distinctive voices in contemporary British theatre. She first gained recognition in 2010 for Roadkill, which won an Olivier Award, and her later plays, such as Swallow (2015), Girl in the Machine (2017), and Enough (2019), have been staged internationally. While each of these pieces attests to the playwright’s ability to confront such urgent social issues as technology, gender, and identity, the focus of her 2016 play Human Animals is on humans’ fragile relationship with animals and the wider environment. By foregrounding animals as literal and symbolic agents, the play challenges its audiences to reconsider the boundaries between human and non-human animals, and the ethical implications of survival. In this interview, conducted in December 2025, Tuğba Aygan talks to Stef Smith about Human Animals. Their discussion highlights Smith’s creative process, thematic concerns, and her insights into our relationship with non-human animals.
