Good and bad news. It Follows director David Robert Mitchell is returning to horror, but he’s only writing the screenplay.

THR says that Mitchell is adapting a feature version of the short film “They Hear It” for Legendary Entertainment and producer The Picture Company.

Created by Julien Terry as a proof of concept short, the film will be turned into a feature by Legendary and The Picture Company on which Terry will make his directing debut.

The premise: there is a mysterious and terrifying noise called The Sound that attracts children when they hear it.

Full plot details of the feature version are being kept under wraps, but sources compare the story to It and A Nightmare On Elm Street, films that explore an ominous presence that stalks the youthful inhabitants of a small community. Interestingly, Mitchell’s It Follows shared similar themes and also harkened back to Elm Street.

The Picture Company’s Alex Heineman and Andrew Rona will produce the film, and Jacob Chase will be executive producer. Chase is the writer/director behind another high-concept horror short turned movie project – Larry, which Amblin Partners picked up earlier this year to shoot in the fall. The Picture Company is also producing that one

This is a big step for Terry, who won New Line’s short film contest to promote Annabelle: Creation. Terry won for a two-minute short he created for the contest about a horror character called The Nurse. His short film Whisper also got a lot of attention in the genre community.
