The Room Below Trailer Unleashes a Creature at Home

The first The Room Below trailer puts grief, obsession, and a mysterious creature under the same roof. The horror mystery stars Alyssa Sutherland and Jonathan Rhys Meyers and arrives on Digital and VOD September 1, 2026.

Sutherland plays Mia, a mother grieving the death of her son. She sees a second chance in a young boy who enters her life, but the situation becomes increasingly dangerous as a creature hidden inside her home becomes more difficult to control.

A grieving mother and a missing child

The trailer presents Mia’s reality as something unstable and threatening. Her attempt to replace what she lost draws the attention of a retired detective, played by Rhys Meyers, who is searching for answers about the missing boy.

Director Kurt Martin appears to be balancing a creature feature with a psychological mystery. Rather than revealing everything immediately, the footage lets the monster remain tied to Mia’s grief and the increasingly disturbing choices she makes.

Alyssa Sutherland returns to creature horror

Sutherland made an enormous impression on horror audiences in Evil Dead Rise, and The Room Below gives her another role built around maternal terror, although this time the danger may be coming from both the creature and the mother herself.

The creature was brought to life by award-winning special makeup effects studio Make-Up Effects Group, whose credits include Furiosa: A Mad Max Saga and Talk to Me. Its Digital and VOD release makes it an easy early-September option for viewers looking for a contained monster story with a darker emotional core.

What We Think

The most promising thing about this trailer is that it does not treat the creature as the whole story. Sutherland can shift from vulnerable to deeply unsettling in a moment, and the movie seems prepared to use that range instead of relying only on a late monster reveal.

We are also curious to see how much of what Mia experiences is literal. A story about grief creating a room for something monstrous could work as both creature horror and tragedy, especially with Sutherland at the center of it.
