 The villa of Francisco Franco served as the Harrington household.The cast and director both described the villa's atmosphere as oppressive, with armed guards constantly present to ensure they did not shoot on the upstairs floors or damage the furnishings.The discothèque scenes were filmed at Balcazar Studios, also in Barcelona, before the crew moved on to the Villa Frascatti in Rome in order to shoot the scenes at the Harrington household which the restrictions at the Franco villa would not allow them to capture.
