Warning: Major spoilers ahead for The MonkeyOsgood Perkins’ new horror comedy The Monkey is adapted from a short story by horror icon Stephen King, and long-time fans of the author and his many cinematic/TV adaptations know that he routinely has small roles in those adaptations. Perkins’ follow-up to the 2024 smash hit Longlegs has a completely different tone, focusing on extremely gory and convoluted kills tinged with humor as opposed to a dark and haunting narrative. Starring Theo James in dual roles as a set of twin brothers, The Monkey is loaded with scary and violent scenes brought to life by an extremely game cast.
