The zombie is the tulpa most typically used to highlight socio-political subtext in horror films. The undead creature and its mythos have been used to highlight subjects as diverse as Slavery, the Vietnam War, rampant consumerism, the military-industrial complex, and ecological disasters. This chapter looks at the Catholic Zombie, a subgenre of zombie film from Roman Catholic countries on the European mainland, exploring criticism of Roman Catholicism and the colonial history of the Roman Catholic Church. Despite the vast amounts of research and writing by film scholars on the subject of zombies, the (anti)Catholic themes present in the European zombie horror film remain under-explored in studies of the subgenre. After highlighting the Catholic coding of the zombie (the perversion of the resurrection myth; the biblical apocalypse of Revelation), semiotic analysis of key zombie horror films from Spain, France, and Italy (all devout Catholic countries) underscores Roman Catholic themes and subtexts by directors operating in a state of apostasy (a conscious uncoupling from one’s church and faith) or otherwise critical of the political power of the church in their home territory, and of its colonial past. The analysis adds nuance to our understanding of the nature of the zombie by providing a wealth of evidence of Catholic coding in the subgenre as a whole and of the (anti)Catholic messaging inherent in European zombie films. This same analysis also provides evidence that, due to the nature of the Roman Catholic church (colonial, patriarchal, socially conservative, and capitalistic) and the ongoing influence of the religion across the globe, this European strand of the zombie film is cyclically relevant and ripe for semi-regular reappraisal, in new times and under new contexts.
