Joe Lederer/Twentieth Century Fox Film Corp.Ryan Reynolds in “Deadpool.” “Deadpool 2,” due in theaters in early 2018, could give 20th Century Fox another “X-Men” movie franchise if the studio plays its cards right. Lost in all the recent drama of changing directors (“Deadpool” director Tim Miller has been replaced by “John Wick’s” David Leitch) and possible differences of opinion on what the sequel’s budget should be (star Ryan Reynolds is said to want it closer to “Deadpool’s” $58 million, while rumors had Miller wanting $100 million-plus) is that “Deadpool 2″ could be a bridge to a new X-Force movie franchise. In a post-credit scene at the end of “Deadpool,” Reynolds name-dropped Cable, creating some X-Force buzz and excitement for fans.
