Although Disney now has the rights to the X-Men and various other characters previously owned by Fox, the company revealed it took a massive hit from the release of Dark Phoenix, which bombed at the box office. It seems pretty unlikely that a lot of Fox's planned X-Men films will ever see the light of day, and we've compiled a list of all of them.
X-Men Origins: Magneto
After Fox's success with X-Men and X2: X-Men United, the studio was eager to capitalize on its success with spinoff films built around the series' most popular characters. The natural first choice was Wolverine, but series antagonist Magneto was next in line to receive his own film.
Ian McKellen's charismatic performance helped make Magneto incredibly popular, and the opening flashback from X-Men -- in which a young Erik Lehnsherr is separated from his mother at Auschwitz -- made audiences interested in his tragic backstory. When the third X-Men filmed opened with another flashback of Magneto, this time with McKellen aged down via CGI, there was excited chatter about the possibility of the older Shakespearean actor taking the main role. Unfortunately, X-Men Origins: Wolverine proved so disappointing across the board that X-Men Origins: Magneto was scrapped. Luckily, some of its ideas survived and were recycled for X-Men: First Class.
Channing Tatum's Gambit
Part of the reason X-Men Origins: Wolverine crashed and burned so hard was the sheer number of characters stuffed into it, hoping to create interest in spinoffs. Gambit appeared in the film, played by Taylor Kitsch, alongside such other characters as Deadpool, who was played by Ryan Reynolds. However, the movie actually ended up hurting the futures of several different characters.
While Deadpool eventually recovered, the planned Gambit solo film limped along in development hell, with Channing Tatum planned to take over from Kitsch. Tatum's starpower kept the project alive for a long time, but the movie's fate is now uncertain following the merger. Dark Phoenix director Simon Kinberg claimed earlier this year Disney was "evaluating" a Gambit movie, but there's a good chance that film's gone for the foreseeable future, with Tatum unlikely to end up in the role.
Logan, which was set in a dystopian future where mutants are dying out, proved a success for Fox across the board, both critically and at the box office, and while the film was the perfect send off for the character Hugh Jackman played for over fifteen years, things were just beginning for Dafne Keen's X-23, a clone of Wolverine. Logan ended on a hopeful note with a band of young mutants setting off north.
Given the character's arc during Logan, there was a lot of potential for where the character could go in her own film. Due to her traumatic background -- which involved excruciating experiments and social isolation -- the often portray X-23 as alienated from her fellow classmates, and that might have made for a deeply interesting film.
Logan was not the only Fox success with sequels cutoff by Disney's acquisition. After Deadpool 2, the studio was already well on its way to rebuilding its brand. Deadpool 2 saw the titular antihero put together a band of mutants (and Peter) he called X-Force, and since the film barely spent any time on most of its members, an X-Force film had sky-high potential.
X-Force would have seen the returns of Cable, Domino, Shatterstar, Bedlam and more. Each of them has potentially interesting stories worth exploring, though this film seems dead, even if there does seem to be some hope Ryan Reynolds might still play Deadpool in the MCU.
Not all of the X-Men spinoffs Fox had planned were based on previously established characters. While Multiple Man was briefly introduced in X-Men: The Last Stand, the character's appearance was incredibly brief, and the solo film would have likely had almost no relation.
With James Franco attached to the role at one point, audiences would have seen his ability to play off his own performance, such as in HBO's The Deuce, multiplied. In the comics the Multiple Man became a private investigator who started his own agency called X-Factor during Peter David's much-beloved run on the series. Given David's deft characterization, any movie drawing from his work could have potentially been very interesting while also including fan favorites such as Siryn, Monet, Strong Guy and Wolfsbane.
The New Mutants Sequels
Perhaps in the weirdest position of any of Fox's planned spinoffs is The New Mutants, which unlike the others previously mentioned actually went through production and is still technically planned for release in the next year. Promising a take on the series in line with the horror genre, The New Mutants focuses on the original team from the comics.
While Sunspot appeared in X-Men: Days of Future Past and Magik's brother is the popular Colossus, other characters from the team had yet to receive even a cameo in the previous Fox films. If the film is ever released it will see the big screen debut of team leaders Cannonball and Mirage, but with the release date continually pushed back and the Disney acquisition putting the film's status up in the air it remains to be seen just what the movie's fate will be. However, director Josh Boone imagined a trilogy of films, which seems impossible at this point.
In addition to all those films, Fox was also looking into movies based around Canadian super-team Alpha Flight and a movie centered around Kitty Pryde/Shadowcat. Although those characters will probably make their way to the MCU in the future, Fox's versions of those films are, at this point, dead. Just how far into the world of mutants Disney plans to delve now that the property is under its umbrella isn't clear, but it's safe to say that the possibilities are X-tensive.
