 The building used for exterior shots of the Black family's home is different from the one seen in "Pilot"; the earlier house was located in an expensive neighbourhood whose residents had decided not to allow filming to continue there. The new location chosen was one which had already been used in Millennium's sister show The X-Files, appearing in that series'second episode "Deep Throat". The house's owner was an air stewardess who would frequently meet members of the cast and crew as they travelled in and out of Vancouver.
