In the modern age, Lovecraftian or eldritch horror has become more and more popular, with increasing numbers of films representing this particular subgenre of scary movie. Named after the works of H.P. Lovecraft, Lovecraftian horror refers to stories that lean on the specific tropes emblematic of the writer's work, including forbidden knowledge, cosmic dread, the insignificance of humanity, and creatures or entities that exist outside the boundaries of human perception. Also referred to as eldritch horror, this particular brand of scary movie has become incredibly popular in recent years.

The best Lovecraftian horror films delve heavily into the themes of Lovecraft's original works, or at least have a superficial surface-level relation to them on the grounds of imagery like Cthulu, the cephalopod-like entity and famous horror antagonist. Some eldritch horror movies are direct adaptations of Lovecraft's stories, whereas others simply take heavy inspiration from the genre while still ultimately creating something new.
