The New Mutants is currently undergoing reshoots and Stranger Things star Charlie Heaton is declaring that it will be a "full-fledged" horror movie set in the X-Men universe. However, New Mutants didn't originally start that way, even if the first trailer led viewers to believe that it was. The new intense reshoots have pushed the film back almost a year and a half to completely reshape it into a horror movie, according to sources, and it seems that this will be the scariest thing to ever come out of the X-Men universe.

In a new interview, Charlie Heaton, who portrays Cannonball, confirmed that New Mutants is going to be something pretty unique. The actor obviously can't say much about the highly anticipated movie, but what he does say is very intriguing to say the least. Heaton goes on to say that New Mutants will be the "scariest thing we've seen" in the comic book movie genre.

"It's basically about these mutants in a facility for damaged mutants. It's a story about these characters coming to grips with who they are and it's a horror X-Men movie, which we haven't seen before. I feel like, for an X-Men movie, yeah, I think they're going full-fledged horror. Without saying too much, I really don't want to give away too much what it's about, it's very under wraps, but it is, in terms of anything we've seen in the X-Men world, it definitely is a horror film. It's scarier than anything we've seen in that genre."

The horror genre is doing big business lately after the massive success of Jordan Peele's Academy Award Winning Get Out and Andres Muschietti's big screen adaptation of Stephen King's IT, which is the highest grossing horror movie in box office history. Additionally, John Krasinski's A Quiet Place is seeing surprise success at the box office after debuting at number one. So, taking New Mutants and fully embracing the horror elements could be a pretty wise decision.

Director Kevin Smith recently spoke about the desire to see a horror-version of a Batman movie based off of the Arkham Asylum storyline, which could end up as a possibility if New Mutants proves to be a success at the box office. The mixing of horror elements into comics is nothing new, but it has yet to be fully embraced on the big screen, though Sony's Venom could slide into that territory when it's released this October.

Fans have been waiting a long time to see the movie and the trailers looked very promising, so hopefully the reshoots will be able to sculpt the new narrative that they've decided to embrace.
