20th Century Fox commissioned a screenplay for a movie based off Marvel Comics' X-Force team back in 2013. The project continues to slowly progress through the movie production process. We've learned that the team would have five members and it's been stated that Cable and Deadpool would both be members of that team.
Earlier today, movie concept art began circulating on Facebook featuring what appears to be the team that will be appearing in the "X-Force" movie:
No Deadpool (though it wouldn't surprise me if he appears in the "X-Force" movie given the upcoming "Deadpool" movie). The concept art features Cable, Domino, Cannonball, Warpath, and some additional female character.
It was suggested that the unidentified woman might be Rogue, Hope Summers, or Psylocke. Personally, I think that the unidentified woman is either X-23/Wolverine or Feral.
