The 1981 horror film, Halloween II, primarily utilized locations within the state of California for its production. This sequel to John Carpenter’s original Halloween sought to recreate the atmosphere and continuity established in its predecessor.
Filming in California offered several advantages, including access to established film infrastructure, experienced crew members, and diverse locations suitable for simulating the fictional town of Haddonfield, Illinois. Specific locations were chosen to mirror the aesthetic of the first film while introducing new settings relevant to the plot, such as the hospital setting.
