Trivia: At the start of the scene where Deadpool and Weasel are recruiting the X-Force, they are looking at photographs of the applicants. The first photo shown is of Ruth Bader Ginsburg, an Associate Justice of the Supreme Court. A closer look at the photo will show that her superhero name is Notorious R.B.G. (00:53:55)
Continuity mistake: In the final fight, Deadpool says to Cable "did you feel that too?" and there's no-one behind them at all. Cable moves forwards to kill a guy on the ground, and a fraction of a second later, as Deadpool says "only best buddies execute paedophiles together" an orderly has appeared in the background, who gets shot.
