He is the author of Monsters in the Closet, which deals with the portrayal of gay men in American horror and science fiction films, with the creation of what Benshoff calls the "monster queer" identity, which Benshoff posits as a counter-hegemonic identity to the heterosexual status quo.[2][3][4][5] In this work, he argues that the films of Val Lewton in the 1940s, such as Cat People, reflected "a growing awareness of homosexuality, homosexual communities, and the dynamics of homosexual oppression as it was played out in society and the military" during that era, which led to a more nuanced depiction of monsters in films of that era.[6] In 2022, he was interviewed for Queer for Fear, a 2022 documentary on LGBTQ representation in horror films.[7]
He has also written books about the blaxploitation and the presentation of race in American horror films.[1]
