Development In 2009,
X-Men film series producer
Lauren Shuler Donner revealed to
/Film her interest in a film adaptation of the
New Mutants comics but that it had yet to be
pitched to
20th Century Fox.
Disney acquisition Reshoots for the film were slated to begin by the end of September 2018, with Kinberg stating: "audiences really embraced the notion of a superhero movie or a comic book movie that was, in its core, a horror film". Following the
acquisition of Fox by Disney in March 2019, it was revealed that the additional photography had still not taken place, nor were they "planned so far". The work was dependent on Boone's involvement, and decisions being made to instead release the film on one of the streaming services owned by The Walt Disney Company. A month later at
CinemaCon 2019, Disney confirmed that the film will be released, but indicated that its release date could be adjusted to better fit within Disney's existing schedule. A month after that, the studio pushed the film's release back to April 3, 2020, and the reshoots were set to take place later in 2019. Kinberg explained that they had take time to reschedule because the creative team was still deciding what portions of the film to reshoot due to the difficulty of reuniting the cast given their busy schedules. In August 2019, Disney was reported to be unimpressed with the original cut of
The New Mutants, believing it had "limited box office potential". Additional work was completed, after Disney acquired it, to align the film with Boone's original vision, and test screenings with these changes had been positive. In addition to making the film more horror-tinged, these changes also included removing overt connections to the
X-Men films. However, the film as released does make reference to the previous entries, with the inclusion of the Essex Corporation connecting the film to the post-credits scene of
Apocalypse and to
Logan. By December of the same year it was confirmed that work on the film had been taking place, while marketing had been adjusted to align with the style of
Marvel Studios. Boone stated that the latest version of the film followed his original vision. In January 2020, Disney's official
fan club website
D23 described the film as a "new addition to the
Marvel Cinematic Universe (MCU)", a statement that was quickly picked up by fans and reporters. Soon after, all mentions of the film were removed from the website, while Disney identified this as an error and stated that the film would not be part of the MCU.
Final cut On March 7, 2020, Boone stated that the film was complete. Shortly after, he explained that work on the film had halted when Disney's acquisition of Fox had begun and so no reshoots ever took place on the film, not even standard pickups that had already been scheduled during initial production. At the time, around 75 percent of the film had been edited while much of the film's visual effects were also not finished. By the time the acquisition was completed, Boone had moved on and was about to begin work on a new television series
The Stand (2020–2021). Before he started production on that series, Disney asked Boone if he would return to finish the film. Rundell and Sullivan were committed to working on
The Stand at that point and could not continue editing
The New Mutants, so Boone brought on editor Andrew Buckland to help finish the film. The work required to finish the film when Boone returned involved completing the visual effects and editing alongside co-writer Lee, which took several months. Reshoots for the film could have been scheduled at that point, but Boone found that the three-year wait since principal photography meant that the young cast had aged too much. He also felt it did not make sense to add the post-credit scenes of Banderas since it was unlikely that they would be able to make a sequel now that Disney owned the X-Men rights and was integrating the property into the MCU. Describing returning to the film after so long, Boone said, "we hadn't seen it in a year. We did a bunch of things here and there that we hadn't thought about or noticed a year before." The visual effects that still needed to be finished included Illyana's sorceress abilities, including her Soulsword that she materializes, as well as her dragon companion Lockheed. Visual effects for the film were provided by
DNEG,
Method Studios, and
Moving Picture Company, with Olivier Dumont serving as VFX supervisor. After the film was completed, Boone reunited the cast for the first official screening in New York City, after which Williams stated, "The movie is exactly the movie we set out to make." Disney removed
The New Mutants from its release schedule, along with several other films, on March 12, 2020, due to the
COVID-19 pandemic, and was looking to reschedule the film's release to a later 2020 date. On May 4, the film was automatically listed for home media pre-order on
Amazon based on the film's previous April 2020 release date. Amazon took the listing down hours later after it had been widely reported on. At that time, the film was still expected to receive a theatrical release rather than be released straight-to-streaming as other films had been during the pandemic. Shortly after, Disney scheduled the film for release on August 28, 2020.
