The film's original director, 'Joe Dante', approached
Nigel Kneale to write the film while Kneale was temporarily living in Hollywood writing the remake of
Creature from the Black Lagoon (1954) for director
John Landis that was never made due to budget cost. Dante wanted a new and different story than the two previous films in the series, so he suggested Kneale write a treatment around the word Halloween. The producers liked the idea, and after Joe Dante moved on to another project, producer
John Carpenter's regular collaborator,
Tommy Lee Wallace, came in as the new director. Kneale initially blamed the drastic changes to his script on executive producer 'Dino De Laurentiis' not understanding his dialogue when it was translated to Italian. Kneale requested his writing screen credit be removed once his comical mystery screenplay was rewritten by an uncredited Carpenter, and then later Wallace (who received sole screen credit as writer), to include more gore and simplify the story.
