Standing as one of the best horror movies of 2024, as well as one of the most gruesome, The Substance is undoubtedly worth checking out for those with strong stomachs. The premise is out there but works surprisingly well, following an aging actress who's given the opportunity to effectively create a new, younger body… but both bodies have to share the same mind, only one can be awake at a time, and they have to alternate 50/50 between being awake and unconscious.
It's also a movie that feels as though it borrows elements from other films, especially those in the horror genre, and blends all those things into its own gooey, messy, and fascinating experience. There are various influences from older movies at hand, and other films that scratch the same itch The Substance does because of their content and/or thematic material. Some of these are outlined below, all being worthwhile watches for anyone who liked The Substance.
