Just thought I'd let everyone know...AN X-FORCE MOVIE IS INDEED HAPPENING!! Don't believe me? Have a look at Imdb- http://www.imdb.com/title/tt3053198/
And Cable will in fact be in the upcoming Deadpool movie! http://www.imdb.com/title/tt1431045/
The group was originally a revamped version of the 1980s team, the New Mutants. Led by Cable, X-Force was a more militant and aggressive group compared to the X-Men. The X-Force arrangement was effective in the early 1990s, however its prominence melted away after Liefeld left, which caused Marvel to implement several reforms to the title from 1995 until 2001 with varying degrees of success.
The current members of the X-Force are Cable, Doctor Nemesis, E.V.A., Fantomex Marrow, and Psylocke. The former members did include Deadpool, Domino, Wolverine, X-23, Nightcrawler, Storm, Deathlok, Boom Boom, and many, many more.
I love how more comic book teams are being established in the movie industry. For example, Avengers, Guardians of the Galaxy Justice League, and even Agents of Shield.
