There’s Someone Inside Your House has a memorable roster of characters — here’s your guide to who they are and the cast members who play them. Netflix original films have been tackling various genres, horror now included. All horror films, no matter their story, need a solid cast of characters for them to work. There’s Someone Inside Your House has a fantastic cast, each of whom plays an integral role that drives the narrative forward.
The horror film, directed by Patrick Brice, takes the genre to another level with technology as the killer dons the faces of the people they’re going to kill that were acquired by way of 3D printing. The story follows Makani Young, a transfer student to Osborne High School. When students start being murdered, Makani also becomes a target of the killer, who goes after those who harbor secrets.
While Makani is the main character who gets primary focus, the horror film ensures she isn’t alone, with actors who play her friends (as well as the supporting cast) being utilized to flesh out the world and central story. Some of the cast might be familiar to viewers while others are lesser-known. Here’s a complete list of the cast and characters in There’s Someone Inside Your House.
