In the commentary track for Deadpool 2, co-writer Rhett Reese admitted that the Passion of the Christ joke that Deadpool (Ryan Reynolds) made in the film was risky -- but probably not for the reasons you're thinking. Team Deadpool weren't worried about backlash from religious fans -- after all, there is not much about Jesus himself that could be construed as offensive in the line. Instead, the joke -- which compared Deadpool's box office performance to that of Mel Gibson's controversial religious movie -- was risky becuase if another surprise hit (like, for example, Deadpool) had come along in the time between filming and releasing the movie, the joke might have been outdated.
