The original Halloween (1978) film was primarily filmed in Southern California, especially in South Pasadena, Pasadena, Hollywood, and Sierra Madre. The fictional town of Haddonfield, Illinois, was created by blending various real locations around Los Angeles and nearby suburbs. Notably:
- Michael Myers' house was originally located at 709 Meridian Avenue in South Pasadena but was later moved to 1000 Mission Street in South Pasadena.
- Laurie Strode's house is at 1115 Oxley Street in South Pasadena.
- Other filming locations include Meridian Avenue & Mission Street, Garfield Elementary School in Alhambra, and the cemetery at Sierra Madre.
- The film was shot mainly in May 1978 over about 20 days.
These authentic locations in Southern California gave the film its iconic look despite it being set in a fictional Illinois town.
