We had loved this X-Men spinoff, The New Mutants. We had loved Bill Sienkiewiczs run with Chris Claremont that had Demon Bear. It was really dark, interesting, and different from the typical X-Men stories that we had read.
After I made The Fault in Our Stars, we made Fox a comic book. It walked them through a trilogy of New Mutant films that would build on each other. We used this program called Comic Life, and took all the images we had loved from the series and strung them together to show them the movie we wanted to do.
We brought it to Simon and he really liked it. Weve been going for the past year and a half to get it ready, and Im about to go location scout and we have a release date now (...)
With New Mutants, we wrote a few drafts, and I brought in Scott Neustadter and Mike Weber, who are the friends of mine that adapted The Fault in Our Stars, to do a draft while we did something else. My guess is that it will never be done until were done shooting! [Laughs]
Its a different experience, because on my last two movies I went into shooting them with very locked scripts. I knew every beat of what they were going to be. This has been different because its constantly morphed as weve gone along. It will probably continue to morph as were making it.
