X-Force was a planned spin off to the Deadpool films as well to the X-Men film series. The film was going to have Josh Brolin and Zazie Beetz reprise their roles from the previous two films.
Following the events of Deadpool 2, X-Force would to continue to fight crime.
In July 2013, 20th Century Fox announced a film version of X-Force. It was also reported that Jeff Wadlow was hired to write and direct the adaptation. Lauren Shuler Donner and Matthew Vaughn signed on as producers. In December 2013, Rob Liefeld confirmed that Cable and Deadpool would be appearing in the film. The film was planned to be released sometime in the year 2017. In December 2015, a piece of concept art was leaked, showing Cable, Domino, Warpath, Cannonball, and Feral as members of the team. In February 2016, Reynolds felt that Deadpool would soon be in an X-Force film, and Kinberg stated that there was potential for X-Force to be R-rated like Deadpool in contrast to the PG-13 "mainline X-Men movies". In May 2016, Bryan Singer stated in an interview with Fandango that he would like to see X-23 to appear in the film as the new Wolverine. And Psylocke was rumored to appear in the film as she is a very prominent member of the team in the comic books; however, actress Olivia Munn (who plays Psylocke in the film X-Men: Apocalypse) never addressed these rumours.  In November 2016, Kinberg announced to The Hollywood Reporter that the film is still on their schedule. In February 2017, it was reported that Ryan Reynolds would co-write the script with Joe Carnahan. In September 2017, Drew Goddard was brought on to write and direct X-Force. In February 2018, Hollywood North Buzz reported that the film would start shooting October 2018 before the Disney/Fox deal is finalised. In May 2018, Deadpool 2 co-writer Rhett Reese confirmed the X-Force movie will be an R-rated take on X-Men and will have "all the sex, violence, and silliness one would expect from the Deadpool-skewed militarized mutant force". Reese said "they can get their hands dirty a little bit. There's more gray area. It'll be raunchier, it'll be rated R, I'm sure. We'll get to see an ensemble movie that's pushed, hopefully, as far as the Deadpool individual movie was pushed." In January 2019, all Fox Marvel properties were postponed until the Disney–Fox deal closes. In March 2019, the deal was officially completed.
