Kinberg is making his directorial debut with X-Men: Dark Phoenix, which stars Jessica Chastain and aims to retell the defining Dark Phoenix storyline from the early 1980s comic book. The prequel saga last left off with X-Men: Apocalypse in 2016, but was set to continue with X-Men: Dark Phoenix this year. More on the Dark Phoenix and New Mutants delays below.
New Mutants has also been delayed, moving yet again after being delayed from its April 13, 2018 release to February 2019. Here's the problem: X-Men: Dark Phoenix has a rather high-profile cast. "That wasn't enough time, and so Fox made a decision to push Dark Phoenix's release date to February to give everyone the time necessary to complete the needed additional photography". The Tracking Board even suggests that New Mutants could end up premiering on Disney's new streaming service and bypass a theatrical release altogether.
Still, considering the lacklustre box office performance and reviews, Fox may be giving the film some extra time to make sure it's the best it can be - whether this is to do with editing, reshoots or tweaks.
Finally, the animated film Spies in Disguise has moved back from January 18, 2019 to April 19, 2019, while the Chrissy Metz movie Breakthrough from director Roxann Dawson and producer DeVon Franklin will arrive on April 12, 2019.
Collider reports that at least 50% of "New Mutants" needs to be reshot. While this new release date still falls within the awards season window, it shows a lack of confidence in the movie's ability to compete during the holidays. Studios shuffle release dates all the time, but these are two of Fox's most highly anticipated films on the docket, so many are rightly wondering exactly why these release dates are being pushed.
