Krasna asked Stanley Donen if he wanted to direct while the latter was making "Kiss Them for Me" with Grant. Donen agreed "but only with Cary". Grant agreed but only if his co-star was Ingrid Bergman (the two had last acted together in "Notorious" ). Bergman agreed provided the film could be shot in England, as she had a theatre commitment in Paris. Krasna agreed to make the changes from the play. Donen and Grant formed a company together, Grandon Productions, to make the film. In September 1957 Bergman announced she and Grant would star in the film for Warners.
