Watch Trailer For X-Men's Horror Spinoff 'New Mutants'

"The New Mutants" celebrated Friday the 13th in style by dropping its first trailer, giving fans a first look into what a horror movie set in the "X-Men" world looks like.

2017 has been good to the X-Men. Legion was a head-trip, The Gifted somehow turned out to be good despite its drab trailers (I know, right?) and Logan was hands-down one of the best films this year. I'm hoping this works out.

Josh Boone warned us.

If you ever wanted to see a cross between a superhero fare and a horror film, you are in luck.

In our spookiest month, Fox has just dropped the official trailer for The New Mutants. Five children are unwillingly kept in a "hospital" where Dr. Cecilia (Alicia Braga) asks them intimate questions about odd occurrences and mutants.

Created by Chris Claremont and Bob McLeod in the early 1980s, The New Mutants was the first "X-"Men comic spinoff".

The trailer is darker than anything in the X-Men cinematic universe so far, something which was Boone's thought process all along. While the villain of New Mutants has yet to be officially confirmed, casting calls indicated Demon Bear and Warlock as possibilities (Demon Bear was part of Boone's original pitch for New Mutants, after all).

Based on the eponymous '80s comic, the film finds a number of young mutants (including Game of Thrones' Maisie Williams) who appear to be trapped in a mysterious hospital. 18 through 20) - is a very simple story: Danielle Moonstar, one of the new mutants of the series' title, faces off against the monster who had killed her parents and, with the help of her fellow students, defeats it.
