According to a March 1957 Hollywood Reporter news item, Twentieth Century-Fox bought the rights to Ronald Alexander's play as a vehicle for Clifton Webb. Although the play was set in European tourist spots, the studio decided to change the film's setting to South America. An August 1957 Los Angeles Times news item announced that Suzy Parker was signed for a role in the picture, and the studio was considering Bing Crosby for a part, but neither appears in the released film. In November 1958, the studio was dickering with Maurice Chevalier to play the role of "Eduardo," according to a Hollywood Reporter news item.
A December 1958 Hollywood Reporter news item announced that Diane Varsi was to play the part of "Meg," but she refused the role, according to a January 1959 Hollywood Reporter news item, and soon after retired from the film business and moved to Vermont. Varsi's last film before leaving Hollywood was Compulsion . Diane Baker then was announced as Varsi's replacement. January and February 1959 Hollywood Reporter news items note that Gene Tierney was originally to play the role of "Mary," but was forced to withdraw because of illness. The studio then started negotiations with Joan Fontaine, but when those collapsed, Jane Wyman was signed for the role, her first in three years.
A January 1959 Hollywood Reporter news item reports that background shots were filmed in South America. Studio publicity contained in the film's production file at the AMPAS Library adds that backgrounds were shot in Rio de Janeiro and So Paulo, Brazil. Location filming was done at the Los Angeles International Airport, the Lockheed Airport and Clover Field, all in Los Angeles. The Variety review commented that the "superimposed scenes of the actors against the backgrounds" were not convincing.
