Trivia: This film signifies the fourth official timeline in the Halloween film series. There is the standard timeline which includes entries 1, 2, 7 and 8. The "Thorn Cult/Curse" storyline which includes entries 1, 2, 4, 5 and 6. And the remake timeline which includes the 2007 film and its 2009 sequel. The new timeline created by this film will only be comprised of the original and this 2018 release.
Trivia: This will be the first film in the franchise with direct involvement from series creator John Carpenter since 1982's "Halloween III: Season of the Witch." Carpenter will serve as an executive producer on the film, in addition to writing the film's musical score. Carpenter, dissatisfied with the prior sequels and the 2007 remake, sought out to return to the series and guide the direction this film went in.
Trivia: Spoilers. Several moments in the climax directly mirror events from the original film, though with reversed roles. For example, in the original Michael falls off a balcony and then disappears when Loomis goes to check. In this film, it is Laurie Strode who falls off a balcony and then disappears. Another example being that in the original, Michael appears from the shadows behind Laurie in a doorway, whereas again in this film, Laurie appears behind Michael from the shadows in the same manner.
Trivia: At one point, an alternate opening was planned that would have picked up at the ending of the original when Dr. Loomis shoots Michael... except it would continue on, and show Michael getting the upper hand and killing Dr. Loomis. Laurie would then grab Loomis' gun and shoot Michael one final time, knocking him out, before the police arrive and apprehend him. Executive Producer John Carpenter protested, and the new opening seen in the film was written to replace it.
Trivia: Spoilers: The film's original ending was quite different. Originally, rather than Michael being burned in the basement, he would instead get into a knife-fight with Laurie outside of the house. After a brief tussle with Laurie, he would then be shot through the chest with a crossbow-like weapon by Karen. The film would end with Michael sitting down, bleeding profusely from his wounds and breathing in slow, heavy manner (implying he's dying) while Laurie, her daughter and her grandaughter drive away into the night. This ending was disliked by test-audiences, and thus the film's theatrical ending was shot to give it a more action-packed finale.
Trivia: When it was originally reported that Danny McBride would be a co-writer on the film, many assumed it was referring to the screenwriter Danny McBride, whom wrote several entries in the "Underworld" film series. It wasn't until shortly after that it was revealed that the Danny McBride co-writing the film was indeed the comedy actor best known for films including "Pineapple Express" and "This is the End." McBride is a huge fan of the original film, and together with director David Gordon Green, wanted to make a proper sequel to the original film after finding the other sequels hit-and-miss.
Trivia: Prior to production on this film beginning, there were a number of other "Halloween" films that were considered. A third film in the remake series under the working title "Halloween 3D" was considered with director Patrick Lussier at one point. After the production fell apart, writers Patrick Melton and Marcus Dunstan began work on a film set in the original series continuity entitled "Halloween Returns," which would follow Michael escaping from prison during an attempted execution and tracking down two specific targets with ties to his past. However, when Blumhouse got the rights to the series, this project was dropped in favor of a more direct sequel to the original film.
