X-Men is now the longest running comic-book movie series in the world, which is especially impressive considering the fact its never been rebooted or covered old ground like the Batman, Spider-Man or Superman franchises. Instead there's been a steady stream of stories loosely adapted from the source material, such as X2s variation on God Loves, Man Kills and Brett Ratners semi-digested Dark Phoenix saga. With mixed results, obviously. Recent rumour has it that Bryan Singer is already gearing up to direct a seventh X-Men film in Montreal in 2017. At this stage its not known exactly what form this latest film will take; It could be Singers next X-Men film as is reported, but since its early days it could just as easily be the long-suggested New Mutants film or a different spin-off entirely, like X-Force. Whichever way things go, were certainly going to be getting a lot more mutants for our money over the coming years, what with Deadpool, a third Wolverine solo film and any number of possible spin-offs in the pipeline. With that in mind, its time we start thinking about some of the places, people and events that havent made it into the X-Men films so far but really should be included.
