The prequel saga concludes in the 1992-set X-Men: Dark Phoenix. In fact, an augmented Wolvie with anger management issues then crops up in the 1983-set X-Men: Apocalypse. Then, while some key scenes in X-Men Origins: Wolverine take place in 1973, the majority of the movie – notably the scenes where Logan gets his adamantium skeleton – is set in 1979.

Ignoring the numerous flashbacks to the 19th century (X-Men Origins: Wolverine) and World War II (X-Men, X-Men: First Class, X-Men Origins: Wolverine, The Wolverine), the mutants’ screen story begins in the 1962-set X-Men: First Class, continuing into the 1973-set X-Men: Days of Future Past. On the face of it, the chronology is fairly straightforward. This is where things get super complex – even supercomputer Cerebro would struggle to get its circuits around the intricacies of the X-Men timeline.
