"What are they?" "The hollow ones... They're watching." Vertical Entertainment has debuted an official Us trailer for a horror film titled The Hollow Child, the feature directorial debut of Jeremy Lutter. Inspired a bit by a folklore tale about children-snatching trolls who secretly hide in the forest, the film is about a foster family that realizes something is wrong with one of them. A troubled foster teen, Samantha, works to expose a dangerous supernatural impostor in her new family and rescue her foster sister. The cast includes Jessica McLeod, Hannah Cheramy, John Emmet Tracy, Jana Mitsoula, Genevieve Buechner, Connor Stanhope, and Johannah Newmarch. This does look like a solid, very eerie forest horror. Watch below. Here's the new official trailer (+ poster) for Jeremy Lutter's The Hollow Child, in high def on Apple: Highly intelligent and malicious creatures known as The Hollow Ones live in the Woods and entice children with their hypnotic folklore music.
