The production was based at Philadelphia's old Civic Center, where production designer Larry Fulton supervised the design and construction of no less than seven individual sets on the area's main exhibition level. On location, the production utilized unique Philadelphia locales such as the historic City Hall, the Undine Barge Club on Boat House Row, Old St. Augustine's Church, Head House Square, Pierce College, Stoddart-Fleischer Middle School, the Presbyterian Medical Center, the Striped Bass restaurant, neighborhoods such as St. Albans Court, and residences and shops along historic streets like Pine, Walnut, Broad, Chestnut, Delancey, and Mt. Vernon.

"Some of the more interesting moments of shooting this movie in Philadelphia," says Mercer, "were those times at two o'clock in the morning on those old, historic cobblestone streets when the eerie shadows of the cascading ivy made you pause and wonder what lost souls might be watching us."
