In a 2024 interview with Macabre Daily, E.L. Katz spoke about his inspirations for the film and the subgenres he was trying to blend: "I love folk horror, but I LOVE survival horror. I think I got to [survival horror] first from slashers. I've watched every single slasher, but the areas that I gravitated to the most were survival [horror]. From the more prestigious John Boorman-y survival to Rituais (1977) and Pouco Antes do Amanhecer (1981). Anything that had people having to swing on ropes, or get trapped by freaky killers in the woods. I just love that stuff so much. Trying to instill this biblical folk horror thing with earthy survival horror was a big goal."
