The exterior shots - both front and back - of what is supposed to be the Puccis' mansion were filmed at 380 South San Rafael Ave., Pasadena, California - the same house used as the exterior of Wayne Manor in the "Batman" series, and which also turned up in episodes of Paramount's sister series "Mission: Impossible," including the second season episode "Charity" and the sixth season episode "The Visitors."
The church shown in the opening shot is the Old South Church in Boston, Massachusetts.
