According to ComicBook.com on Dec. 3, "X-Force" comic book creator, Rob Liefeld, had read the script to the film and tweeted the fact that he thought it was "beyond impressive". Even though Twentieth Century Fox had made no kind of official announcement yet, Jeff Wadlow was brought on board to write the screen play and to possibly direct it, too.
Liefeld has not revealed any real big spoilers, however, he did give some pieces of information in regards to the script.
"The best part of the film is the camaraderie between the team as they learn to cope and trust one another!"
According to the creator, he thinks that fans of Cable, X-Force, and Deadpool "will scream in absolute delight!" Seemingly, it appears that Liefeld's comments may suggest Cable and Deadpools involvement in the film, he refused to expose anymore information about the casting of characters.
Though one would question that if there would be any kind of impact of the "X-Force" upon a stand alone "Deadpool" film, Liefeld sees it as being plausible that these two movies could be spaced apart from six months to one year of each other.
Basically, the comic book premise states that the start of the X-Force team was enacted by Cable, a mutant from the future, who travels to present time to reform the New Mutants into who they are today. They are known to take a more proactive stance for those that stand against mutants.
