Other mistake: In the original ending, after Laurie is pulled out of the cop car, Loomis is able to reason with Michael to let her go. After he does, he is shot to death by the police. This was obviously changed, but when Loomis is reasoning with him in the final cut, you can still see the police standing behind him. (01:46:00)
Halloween (2007)
1 other mistake - chronological order
Directed by: Rob Zombie
Starring: Brad Dourif, Malcolm McDowell, Scout Taylor-Compton, Tyler Mane, Daeg Faerch
Genres: Horror
Continuity mistake: In the beginning, after Michael kills his sisters boyfriend, he puts the mask on with bloody hands yet he gets no blood on the mask.
Dr. Samuel Loomis: Inside every one us, there exists a dark side. Most people rise above it, but some are consumed by it. Until there is nothing left, but pure evil.
Trivia: Aside from the more obvious relations between the original and the remake (i.e. "Don't Fear the Reaper", etc), one interesting one is how Michael acquires his trademark jumpsuit. In the original, it's implied he kills a trucker and steals his (we see his dead body in a field left with Michael's robes). Sure enough, in the remake Michael also gets the jumpsuit from a trucker - of course this time the death is plainly visible.
Question: Why did Michael stop attacking his sister and take off the mask, showing her the picture?
Answer: He was hoping that Laurie would realise that she's really his sister. However, because Laurie was just a baby and raised by another family, she had no idea why Michael was showing her the picture or what it had to do with her.
Suggested correction: The police came anyways. He is a wanted killer, after all.
During the timestamp above, an officer standing behind Loomis with their gun ready while he's talking to Michael, but besides these shots, the officer is nowhere to be found. In the alternate ending, this confrontation is completely different as cops are shown actually pulling up behind Loomis. You are able to see that shots from the alt ending are used in the final movie, thus making the mistake valid.
