The house used for the exterior shots of Halliwell Manor is located at 1329 Carroll Avenue, Los Angeles, California. The same house was used for the exterior of the tall woman's house in Deuce Bigalow: Male Gigolo (1999) and as Hank Pym's (Michael Douglas) residence in Ant-Man (2015). It is located only 350 feet (170 meters) from Angela and Ithyle, Inc. 814 E Edgeware Road which was Joe Hallenbeck's office in "The Last Boy Scout (1991)."
