It seems fair to say that there isn’t another superhero film series more confounding than Fox’s X-Men universe.
From the first X-Men film to the fourth X-Men film (the oft-criticized prequel film X-Men Origins: Wolverine) in 2009, things were clear enough — the actors playing the iconic superhero team remained the same and the story was moving forward on a (more or less) consistent pace.
Going forward, it’s safe to assume this newer X-Men timeline is headed for another convergence: a collision with the Marvel Cinematic Universe.
The first installment of the new (and current) X-Men timeline takes viewers back to the 1960s.
