Ben Wheatley's In the Earth (2021) is a hallucinatory British horror about scientists venturing into the woods during a pandemic, only to confront folk rituals, pagan legends, and psychedelic terror. Mixing folk horror, survival horror, and psychological dread, it builds on Wheatley's tradition of unsettling, genre-bending nightmares.
