The original script for 1978’s Halloween was titled “The Babysitter Murders.” In it, the events took place over several days. The script was changed to have everything happen on the same day as a budgetary decision. It reduced the number of costume changes and locations required. It was decided that Halloween, the scariest night of the year, was the perfect night for this to happen.
Of the female leads (who were all supposed to be in high school), only Jamie Lee Curtis was actually a teenager at the time of shooting.
As a kid, I always loved the look of the Halloween trick-or-treat buckets you could get at McDonald’s, but I was disappointed in their small size. It was probably less than a quarter of what I could get into an empty pillow case. What was the point? lol
Director John Carpenter originally intended to call his movie The Babysitter Murders, but producer Irwin Yablans suggested that the story may be more significant if it were based around a specific holiday, so the title was changed to Halloween. Carpenter and co-screenwriter Debra Hill wrote the original script in just 10 days.
