There has been no shortage of X-Men movies since filmgoers were first introduced to Professor X and company in 2000. Marvel fans have seen the good (X-Men, X-Men: First Class), the bad (X-Men: The Last Stand), and the so sad it might ruin not just all Wolverine movies, but all Hugh Jackson movies for you (Logan). And now, mutant 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.)

With the film, Williams is joining her GoT co-star and real-life bestie, Sophie Turner, in the X-Men universe. Turner 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 weepie The Fault in Our Stars.

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