Question: The events of Scream VI take place around Halloween, but it doesn't specify what year. A news reporter said that the Woodsboro killings took place in 2022 as if they happened a year ago, and Scream VI was released in March of 2023. So, do the events of Scream VI take place on Halloween of 2022 or 7 months in the future after the film's release date?
Answer: Using some conjecture, if the film states the last killings took place in 2022 and treats it like "last year," you can assume it takes place around Halloween 2023. Films are allowed to take place in the future. They don't have to be set around their release date. So how is this a mistake?
Answer: I think this is more "trivia" than mistake. There's no error in a film taking place a bit further ahead in time than in its release date.
