For starters, I’m told that the creative differences between director Josh Boone and Fox execs have been blown out of proportion by fanboy bloggers who are all too eager to make a mountain out of a molehill, and that Boone ultimately delivered the movie that he and co-writer Knate Lee originally agreed to make.
....
At first, Boone and Lee wanted to make a horror movie, but Fox was initially resistant to that idea, as the studio didn’t want to go “full horror.” Sources say that Fox demanded a PG-13 rating and pushed back against the film’s horror elements, such as excessive blood and scares. Eventually, everyone got on the same page, and together, they set out to make a YA movie that felt like a cross between Stephen King and John Hughes. Fox film chief Stacey Snider is basically quoted as calling New Mutants a superhero movie set in a Breakfast Club-like setting whose genre is more like The Shining than “let’s save the world.” And then… It happened.
It was released in early September and did incredibly well for Warner Bros., even beyond the studio’s wildest nightmares, er, dreams. In response, Fox cut a trailer for New Mutants that played up the scary elements from the film, essentially selling it as a straight-up horror movie —
this despite the fact that in its first test screening, New Mutants scored the exact same number as the first screening of Deadpool and besides the very end, reshoots were deemed unnecessary. However, because of that well-received trailer, audiences were now expecting a horror movie.
