The timeline below contains critical spoilers from X-Men: Days of Future Past.
The timeline splits based on a different scenario occurring in the film. Also, the timeline makes it seem like events from every film were more or less erased, but based on director Bryan Singer's comments in the past, that shouldn't be the case and the events of X-Men & X2 should still be intact, although a different variation most likely occurred in the new timeline. Also, with Wolverine & Professor X remembering the alternate timeline, a variation of the events of The Wolverine are likely to still have occurred. X-Men Origins: Wolverine & X-Men: The Last Stand are the two films most affected by the timeline shift.
