Most of the cast and crew disowned this movie. On the Halloween: 25 Years of Terror (2006) DVD, they stated that the studio, producers, and director interfered and argued to the point of ridiculousness which resulted in a very poorly directed and edited film.
It was Daniel Farrands who suggested that the film be called The Curse of Michael Myers due to the troubled production.
The producers of the movie wanted Brian Andrews to reprise his role as Tommy Doyle from the original Halloween (1978). However, Andrews did not have an agent, so they could not get in contact with him, and the part went to Paul Rudd instead. Andrews has stated since that he regrets missing the opportunity. He could have had another shot at playing the part in Halloween Kills (2021), but by that time, he had retired from acting, and Rudd had a scheduling conflict with another movie, so the role was re-cast again.
As a result of Donald Pleasence's death, as well as creative differences between Joe Chappelle and the producer, and an allegedly bad test screening of the original work (the famous producer's cut) re-shoots were done as well as lots of editing, to the anger of most of the cast and crew. Many vowed never to make another Halloween movie again after all the changes.
