Of the many locations that were used in the film, the Rosecliff Mansion was used for the ballroom tango scenes in the beginning of the film and the exterior of the Swiss chalet that Harry Tasker infiltrates is Ochre Court. The ballroom dancing scene that closes the film, as well as the scenes in the lobby of the fictional Hotel Marquis in Washington, take place in the Crystal Ballroom of the Millennium Biltmore Hotel in downtown Los Angeles. The outdoor structures used by Azis's smuggling ring as a base of operations were a series of custom made Alaska Structures fabric buildings, leased to the production crew during filming.
