The filming locations for "Monster: The Ed Gein Story" included several places in Illinois and California. Specifically, the series was filmed in the town of Momence, Illinois, which was transformed to look like a 1950s town, as well as in the village of Saunemin, Illinois. Additional filming took place in Los Angeles, California, and Chicago, Illinois, including the Pullman neighborhood and the Hotel Florence in Chicago. The production moved between these locations during filming in 2025.
For other Ed Gein-related films, such as the 2000 "Ed Gein" movie and the 2007 "Ed Gein: The Butcher of Plainfield," filming took place primarily in California, particularly in the Santa Clarita area, Topanga, and Los Angeles.
