X-Men fans are finally getting a horror movie.

On Friday (the 13th, no less) the trailer dropped for X-Men: The New Mutants — a look at what happens when mutant teens aren't sent to a magical prep school full of small classes and only the occasional government raid, and instead are locked in some kind of haunted house. The film stars Stranger Things' Charlie Heaton as Sam Guthrie (Mutant code name: Cannonball) and Game of Thrones' Maisie Williams as Rahne Sinclair a.k.a. Wolfsbane. (I know it's traditional to pick a new name that highlights your abilities, but Rahne Sinclair is already a pretty cool name.)

From the looks of the trailer, a gaggle of teen mutants are up against something sinister when they realize the hospital they're at has something that goes bump in the night. We get to see a bit of those superpowers that are an integral part of the X-Men universe, but it's more screams and frights than taking down bad guys.

With the film, Maisie is joining her GoT co-star and real-life bestie, Sophie Turner, in the X-Men universe. Sophie played young Jean Grey in last year's X-Men Apocalypse and will star in X-Men: Dark Phoenix, out next November.

If the star power of X-Men: The New Mutants hasn't sold you (the film also features Split's Anya Taylor-Joy and 13 Reasons Why's Henry Zaga), the man behind the camera might. Josh Boone, who directs the new film and penned the screenplay, also directed classic teen flick The Fault in Our Stars.

X-Men: The New Mutants will be released on April 13. Watch the trailer below, if you dare:
