Halloween film franchise history and timelines

The Halloween horror franchise, initiated by John Carpenter’s 1978 film, has evolved into a complex series of 13 movies characterized by multiple distinct continuities. While the original film served as a catalyst for the slasher sub-genre, subsequent entries have included remakes, abandoned storylines, and alternate timelines.

Viewers can navigate the franchise by release order or by selecting specific timelines to maintain narrative coherence. Currently, Michael Myers exists within four separate movie continuities, while the 1982 film, Halloween III: Season of the Witch, stands as a standalone entry. Notable shifts in continuity include Halloween H20, which discarded several previous sequels, and the 2018 reboot, which ignored most films released after the 1978 original.

Beyond the films, the franchise includes a 1979 novelization by Richard Curtis, writing under the pseudonym Curtis Richards. The book attempted to expand the lore by introducing a supernatural origin involving an ancient Irish prophecy and the character Enda, elements that influenced later installments in the film series.
