Trailer for H.P. Lovecraft adaptation Unspeakable: Beyond the Wall of Sleep starring Edward Furlong

March 1, 2025 by Amie Cranswick

Breaking Glass Pictures has shared a poster and trailer for Unspeakable: Beyond the Wall of Sleep, the final chapter in writer-director Chad Ferrin’s Lovecraftian trilogy.

The sci-fi horror follows a renowned oneirologist (Edward Furlong), as he is called to Arkham Asylum to study a disturbing case of a patient with a split personality, where he unknowingly opens a portal to a malevolent alien entity.

The cast includes Edward Furlong, Robert Miano, Susan Priver, Bai Ling, Ginger Lynn, Lew Temple, Steve Railsback, and Cyril O’Reilly. Watch the trailer below…

Inspired by H.P. Lovecraft’s terrifying short story, the film follows Ambrose London (Furlong), a world-renowned oneirologist summoned to Arkham Asylum to investigate a deeply disturbing case—a man possessed by a 122-year-old colonial peasant. But when Ambrose’s “Dream Machine” accidentally opens a portal to an alien entity hellbent on world annihilation, all hell breaks loose in a twisted, nightmarish descent into madness.

Unspeakable: Beyond the Wall of Sleep is set for release on March 4th.
