Trivia for The New Mutants.
- The film's storyline is rumored to have been inspired by the Demon Bear Saga from the New Mutants comics .
- Anya Taylor-Joy, who portrays Magik, previously starred in the 2016 horror film Split with James McAvoy, the actor who portrays Professor X. Much like The New Mutants, Split exists in a shared universe based on superheroes.
- Josh Boone has stated that future sequels to The New Mutants are all going to have distinct horror tones. He also plans to introduce characters like Karma and Warlock .
- The first official trailer for The New Mutants features the song, "Another Brick in the Wall (Part 2)". The opening lines of the songs are: "We don't need no education / we don't need no thought control". This is an inversion of the New Mutants' origin from the comics, where they started out as students at Xavier's School for Gifted Youngsters. Fitting enough, Charles Xavier - the New Mutants' founder - has telepathic abilities that allows him to control the thoughts and actions of others.
