8 Times Superhero Movies Pushed The Boundaries Of PG-13

8. Fox's X-Men F-Bomb Party - Various

The MPPA's PG-13 guidelines do allow for a single use of "one of the harsher sexually-derived words", (though somehow it's hard to imagine Hugh Jackman calling anyone a c**t) and Fox took full advantage of this with some hilarious examples of superhero swearing in their X-Men movies. 

It began with Matthew Vaughn's X-Men: First Class when Wolverine told Xavier and Magneto to "go F-themselves", then we had an "F-you pretty boy" in the Wolverine, and the most recent example was Xavier returning the insult to Logan in X-Men: Days Of Future Past with a nice, straight to the point "F-off". 

Though technically within their rights, Fox still took a chance allowing their superhero characters to drop F-bombs, and writers must be only too happy to see where they can slip them in to future movie scripts. Expect more mutant F'ing and blinding in X-Men: Apocalypse next year.
